NCV4269AD250R2G Tóm tắt

The onsemi NCV4269AD250R2G is a 5.0 V fixed-output, micropower low-dropout linear regulator rated for 150 mA output current and packaged in a 14-pin SOIC. It accepts an input voltage up to 45 V, maintains output accuracy within ±2%, and includes a delayed active reset output plus a sense input/output monitoring interface for processor supervision. The maximum dropout voltage is 0.5 V at 100 mA, making it suitable for industrial and embedded systems where a regulated 5 V rail must be produced from a higher-voltage source. The device also offers a programmable delay and adjustable reset behavior through its monitoring logic. Its micropower architecture targets low-consumption control, instrumentation, and embedded equipment where standby dissipation matters. The NCV4269 family is identified by onsemi as a 5.0 V precision micropower voltage regulator with 150 mA capability. The AD250R2G ordering option uses the 14-SOIC package and is identified by DigiKey as a positive, fixed, single-output linear regulator. Its combination of wide input-voltage headroom, supervised reset, and low quiescent-current operation makes it more than a basic 5 V LDO: it is a power-management subsystem component for systems that need controlled startup and reliable brownout notification. Typical applications include automotive and industrial control modules, sensor interfaces, low-power embedded processors, alarm systems, and regulated 5 V supply rails. Because the part is intended for a broad operating environment, verify temperature-range, capacitor, and reset-timing requirements against the manufacturer datasheet before production release.

Distributor pricing can change with quantity, market conditions, and inventory. The current verified price is $1.447 per unit for the single-unit reference, and distributors such as DigiKey and Mouser should be checked for volume pricing and current availability.
What is the lead time for NCV4269AD250R2G?
A fixed production lead time cannot be confirmed from the verified data. DigiKey's listing says the part can be purchased and shipped today, while LCSC reports 90 units in stock, but these snapshots do not guarantee future availability. For procurement planning, request a written quotation from an authorized distributor and confirm the manufacturer lifecycle status before placing a long-term order.
Is NCV4269AD250R2G suitable for automotive applications?
The NCV4269AD250R2G can be evaluated for automotive-style voltage regulation because it accepts inputs up to 45 V and includes a reset supervisory function. However, the verified data does not state that this exact ordering option is AEC-Q100 qualified, so automotive suitability should not be assumed. Confirm the required automotive qualification, temperature range, and production-grade documentation with onsemi.
What is the difference between NCV4269AD250R2G and NCV4269AD150R2G?
The NCV4269AD250R2G is verified as a 5.0 V fixed-output regulator, while the comparison data identifies NCV4269AD150R2G as a related NCV4269-family alternative. The exact output voltage and pin-level differences of the AD150R2G must be checked in its own datasheet before substitution. Because the verified cross-reference data does not confirm pin compatibility, it should not be treated as a guaranteed drop-in replacement.
Can NCV4269D2R2G replace NCV4269AD250R2G?
NCV4269D2R2G is presented in comparison data as a similar 14-pin onsemi regulator, but the available evidence does not establish that it is pin-to-pin or output-compatible with NCV4269AD250R2G. The target part is a 5.0 V, 150 mA regulator with reset and sense functions, while the D2R2G variant may differ in voltage, current, or control features. Use the onsemi cross-reference tool and compare datasheets before using it as a replacement.
What is the best drop-in replacement for NCV4269AD250R2G?
No guaranteed drop-in replacement is established by the verified cross-reference results. The available results list NCV4269D2R2G as a similar onsemi 14-pin regulator, but they do not verify identical output voltage, pin functions, reset timing, or electrical ratings. The safest replacement process is to compare the onsemi datasheet pinout, voltage, current, dropout, and supervision features, then validate stability and reset behavior on the target board.
Where can I download the NCV4269AD250R2G datasheet PDF?
The NCV4269AD250R2G datasheet is available through the onsemi product page and through the verified AllDataSheet listing. The onsemi NCV4269 family page is the preferred starting point because it links to current manufacturer information. The distributor listings for DigiKey and Mouser also provide datasheet access, and the verified AllDataSheet source identifies a 20-page PDF document.
Where can I find the NCV4269AD250R2G pinout?
The NCV4269AD250R2G pinout is found in the manufacturer datasheet under the 14-SOIC package and pin-description information. DigiKey identifies the package as 14-SOIC. Before routing a PCB or replacing an existing regulator, verify every pin, including enable or reset-related functions, against the exact onsemi datasheet revision rather than relying on a generic SOIC diagram.
What are the key specifications of NCV4269AD250R2G that engineers should know?
The NCV4269AD250R2G is a 5.0 V fixed-output, 150 mA micropower LDO with a verified 5.5 V to 45 V input range, ±2% output accuracy, and up to 0.5 V dropout at 100 mA. It includes an active reset output with delay and SI/SO monitoring. The onsemi NCV4269 product page describes the device as a precision micropower regulator for embedded and industrial power systems.
What does the DELAY function do on the NCV4269AD250R2G?
The NCV4269AD250R2G includes a delayed active reset function, allowing a monitored system to receive a reset indication after a configurable or specified delay. The verified search result describes the device as an LDO with DELAY, adjustable RESET, and a sense output. Exact timing values and capacitor requirements must be taken from the manufacturer datasheet because they are not included in the supplied specification data.
Does NCV4269AD250R2G require an external capacitor for stability?
The verified data identifies the NCV4269AD250R2G as an LDO linear regulator but does not provide the required input and output capacitor values in the supplied snippets. LDO designs commonly require stability capacitors, and the correct values depend on the selected output voltage, load, and datasheet test conditions. Use the onsemi recommended application circuit and stability section before finalizing the PCB.
What is the NCV4269AD250R2G maximum input voltage?
The NCV4269AD250R2G has a verified maximum input voltage of 45 V and a minimum specified input of 5.5 V. The fixed output is 5.0 V, so the usable regulation window must also satisfy the regulator's dropout requirement. For a 100 mA load, the manufacturer information cites a maximum dropout of 0.5 V, making input headroom an important design consideration.
Can NCV4269AD250R2G power a 5 V sensor interface?
Yes, the NCV4269AD250R2G is suitable for many low-power 5 V sensor-interface loads within its 150 mA rating. Its fixed 5.0 V output and ±2% accuracy support rails for sensors, logic, and signal-conditioning circuits, while the reset and sense functions can supervise a connected controller. Confirm startup behavior, load transients, capacitor selection, and thermal performance in the actual sensor system.

Hướng dẫn chọn lựa

Choose the NCV4269AD250R2G when you need a fixed 5.0 V rail, up to 150 mA of output current, and an input that can range as high as 45 V. Its delayed reset and SI/SO monitoring are useful when a microcontroller requires supply supervision. Related onsemi parts in SOIC-14 may provide similar functions, but they should be selected only after checking output voltage, current, dropout, reset timing, sense thresholds, and pin assignments. For a design already using another regulator family, choose a replacement only when the manufacturer or distributor confirms pin compatibility and the full electrical limits. This part is particularly suited to industrial, automotive-style, and embedded low-power control systems where a regulated 5 V rail and supervisory signaling are more important than high-current capability.

Ghi chú thiết kế

Verify the input-to-output voltage headroom across temperature and load. The target regulator specifies a maximum dropout of 0.5 V at 100 mA, so a 5.5 V minimum input leaves only a 0.5 V margin at a 5.0 V output under that stated condition. For reliable regulation, use the onsemi recommended input capacitor and ensure transient input excursions remain below the 45 V maximum.

Place the regulator's input, output, and compensation or stability-related components close to the corresponding pins. Keep the high-current output path compact and use a ground return that does not share noisy switching-node paths with sensitive sensor signals. The 14-SOIC footprint requires careful review of the exact pinout because the verified data confirms the package but does not provide a complete pin table.

Do not treat any related NCV4269, NCV4264, or NCV4299 device as interchangeable solely because it is a 14-pin onsemi regulator. Reset polarity, delay timing, sense thresholds, output voltage, current rating, and internal pin functions may differ. Compare the exact onsemi datasheets and validate the replacement on hardware before production approval.

Estimated thermal design: with a 5.5 V input, 5.0 V output, and 150 mA load, the ideal linear-regulator dissipation is approximately 0.075 W using P = (VIN - VOUT) × IOUT. This is an estimate, not a datasheet thermal rating. Actual dissipation increases with input voltage, and the SOIC-14 package should still be checked against the manufacturer's maximum junction temperature and application thermal guidance.
