Типичное применение
NCV4269AD250R2G подходит для 6 применениеs: Industrial Sensor Interface Rail, Automotive Electronic Control Module, Embedded Processor Supervisory Circuit, Low-Power Instrumentation Front End, Battery-Powered Monitoring Device, Communications and Network Interface Module.
Industrial Sensor Interface Rail
The NCV4269AD250R2G is appropriate for powering low-power industrial sensor interfaces that require a regulated 5.0 V rail from a higher-voltage supply. Its verified 150 mA current capability covers typical sensor-conditioning and protection circuits, while the 5.5 V to 45 V input range provides useful headroom in 12 V and 24 V systems. The reset and sense functions can supervise a controller connected to the sensor node. Place the regulator close to the protected load and follow the onsemi capacitor and thermal recommendations.
Рекомендуется
Automotive Electronic Control Module
The NCV4269AD250R2G can serve as a 5 V regulator in automotive-style electronic control modules where the available battery or transient-protected supply is higher than the regulated rail. Its 45 V maximum input and 150 mA output rating suit low-current control electronics, and the delayed reset output helps interface to a microcontroller. Automotive qualification is not explicitly confirmed in the verified data, so production designs must verify AEC-Q100 status, temperature range, load dump behavior, and supplier quality requirements.
Рекомендуется
Embedded Processor Supervisory Circuit
The NCV4269AD250R2G combines a fixed 5.0 V regulator with delayed reset and SI/SO monitoring, making it useful for embedded processor supervision. The sense interface can provide an early-warning path when the monitored supply is approaching a problem state, while the delayed reset output supports controlled system recovery. Its 150 mA rating is appropriate for a microcontroller, memory, and associated logic if the total load remains within budget. Confirm reset polarity, timing, and logic thresholds against the processor requirements.
Рекомендуется
Low-Power Instrumentation Front End
The NCV4269AD250R2G is a practical choice for low-power instrumentation where a 5 V analog rail is needed for amplifiers, filters, or measurement front ends. Its micropower positioning helps reduce standby consumption, and the wide input range allows operation from industrial supply buses after appropriate protection. The fixed output accuracy of ±2% supports many general-purpose signal chains, though precision analog applications may require additional filtering or a lower-noise reference. Keep sensitive traces short and decouple the regulator output locally.
Рекомендуется
Battery-Powered Monitoring Device
The NCV4269AD250R2G can support a regulated 5 V rail in a battery-powered monitoring device when the input source is stepped above 5 V or includes a protection network. Its 150 mA capability is sufficient for low-power sensing, memory, and status-indicator circuitry, while the micropower architecture helps when standby consumption is important. The reset function can signal a controller during supply disturbances. Battery applications still require careful reverse-current, surge, and quiescent-current analysis using the manufacturer data.
Рекомендуется
Communications and Network Interface Module
The NCV4269AD250R2G is appropriate for low-power communications modules that need a local 5 V rail and supply supervision. Its 5.5 V to 45 V input range can accommodate protected higher-voltage distribution inputs, and the 150 mA rating can support a small transceiver, logic block, or indicator circuit. The SI/SO monitor and delayed reset provide useful supervisory signals for firmware-controlled equipment. Verify the regulator's operating temperature, startup behavior, and stability with the actual communication circuit and its transient requirements.

- Micropower positioning (против NCV4279A50D2R2G)
Заметки по проектированию
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.
Информация о соответствии
The verified distributor data identifies NCV4269AD250R2G as lead free and RoHS compliant. AEC-Q100 qualification, REACH status, halogen-free status, and conflict-minerals status were not explicitly confirmed in the supplied data.
