TS14002-C023DFNR - 2.3V 150mA LDO | Semtech
MPN： TS14002-C023DFNR ✗ 停產TS14002-C023DFNR 概覽
A low-dropout regulator, or LDO, is a linear regulator that maintains a stable output voltage while consuming less power than a switching regulator under suitable low-dropout conditions. In the power-management hierarchy, an LDO belongs to linear regulators, voltage regulators, and power-management ICs. It is commonly used to clean up a supply rail for analog, sensing, communications, embedded, and portable-electronics circuits.
The principal verified characteristics are the 2.3 V fixed output, 150 mA rated output current, and 8-DFN 2 x 2 mm package. The manufacturer describes the TS14002 family as a nanoSmart ultra-low-power linear regulator. These features make the TS14002-C023DFNR relevant to designs requiring a compact, low-power rail, although the supplied data does not include the input-voltage window, dropout voltage, accuracy, noise, current consumption, thermal limits, or capacitor requirements.
Because the available verified results do not expose the complete electrical limits or a manufacturer-hosted datasheet, designers should obtain the official TS14002 datasheet before finalizing a power tree. In particular, verify minimum input voltage, maximum input voltage, output tolerance, line regulation, load regulation, quiescent current, enable behavior, stability, and exposed-pad requirements. The distributor listings identify the exposed-pad 8-DFN construction, making land-pattern and thermal-pad layout verification essential.
Typical application candidates include battery-powered sensors, portable instrumentation, low-power wireless modules, industrial monitoring nodes, embedded control rails, and compact consumer devices. The 150 mA rating is appropriate only when the calculated peak load remains below the manufacturer's specified operating conditions, including line, load, temperature, and package thermal limits.
A valid design must confirm that the upstream supply remains above the regulator's dropout requirement at maximum load and minimum input voltage. Preserve the manufacturer-recommended input and output capacitors, connect the exposed pad according to the datasheet land pattern, and keep sensitive analog routing away from noisy switching stages. This page combines verified distributor information, lifecycle observations, sourcing links, and clearly identified data gaps for engineering review.
For a replacement, do not treat a generic 2.5 V or 3.3 V LDO as interchangeable. The output voltage must remain exactly 2.3 V, and the footprint, enable arrangement, electrical limits, capacitor compatibility, and thermal behavior must match. No verified drop-in alternatives were identified in the supplied cross-reference results, so this record does not recommend unverified substitutes.

典型應用
TS14002-C023DFNR 適用於 6 應用s: Battery-Powered Sensor Nodes, Portable Instrumentation, Low-Power Wireless Modules, Industrial Monitoring Nodes, Embedded Control Rails, Low-Power Consumer Devices.
Battery-Powered Sensor Nodes
The TS14002-C023DFNR can provide a compact 2.3 V rail for sensors and signal-conditioning electronics when its verified 150 mA output rating covers the peak load. Its nanoSmart ultra-low-power positioning makes it relevant to battery-operated monitoring, but battery life cannot be quantified because the input range and quiescent current are absent from the supplied data. Confirm dropout at the battery's minimum voltage and verify stability with the manufacturer's required capacitors.
Portable Instrumentation
The 2.3 V fixed output is suitable for low-voltage blocks in compact measurement products where regulated current stays below 150 mA. The 2 x 2 mm 8-DFN footprint helps preserve board area compared with larger regulator packages. Before implementation, verify the analog circuit's allowable supply tolerance, analog-noise requirements, enable timing, and exposed-pad layout because those specifications are not present in the verified search data.
Low-Power Wireless Modules
TS14002-C023DFNR may serve a 2.3 V rail beside a compact wireless module when peak current remains within the verified 150 mA rating. The regulator's enable capability, noted by verified distributor information, may assist controlled power sequencing, although exact logic levels and timing require the official datasheet. RF current bursts also make input ripple, supply impedance, decoupling, and thermal behavior important qualification items.
Industrial Monitoring Nodes
The fixed 2.3 V output can support low-voltage sensing or embedded-control sections of industrial monitoring equipment. Its small 8-DFN package is useful where board space is constrained, while the 150 mA rating can support modest sensor and communication loads. Deployment should account for the verified not-for-new-designs status, industrial temperature requirements, long-term availability, and transient protection at the board input.
Embedded Control Rails
The regulator can supply a dedicated 2.3 V domain in a compact embedded-control design if its exact pinout, output accuracy, and capacitor requirements match the controller power specification. Enable control can assist system sequencing, but the allowed input range and sequencing delays are not supplied. Prototype only after reviewing the official datasheet and validating startup, load transients, ground return, and exposed-pad thermal performance.
Low-Power Consumer Devices
A 2.3 V rail from TS14002-C023DFNR may fit compact consumer accessories that require a modest, regulated supply in an 8-DFN 2 x 2 mm footprint. The verified 150 mA rating is sufficient only for loads whose peaks and sustained dissipation remain within device limits. Because the part is labeled not for new designs, it is better suited to servicing an existing design than to an unqualified new platform.

主要差異化特點
- Exact 2.3 V fixed-output choice (對比TS14002-C020DFNR)

設計說明
Verify the regulator's minimum acceptable input voltage and dropout requirement against the 2.3 V output before schematic approval. The verified data confirms a 2.3 V, 150 mA device but does not provide dropout or input limits. At maximum load, the input must retain enough voltage for regulation plus the control-loop margin required by the manufacturer. Do not infer headroom from the nominal 2.3 V output alone.
Use the exposed-pad land pattern exactly as specified by Semtech and provide adequate copper for heat transfer. Actual dissipation depends on input voltage, output voltage, load current, package thermal resistance, and ambient temperature, none of which is fully supplied. Measure worst-case dissipation across startup, full load, and maximum temperature rather than applying an unverified thermal estimate. Maintain manufacturing cleanliness around the exposed pad.
Keep the regulator, input capacitors, output capacitors, and load-return paths close together to minimize loop area and supply disturbance. The verified listings do not specify external capacitance or ESR requirements, so obtain those values from the official datasheet before release. Do not assume another regulator's capacitor network is compatible; stability and transient response can differ even when output voltage and package match.
Do not substitute TS14002-C020DFNR or TS14002-C025DFNR as if they were drop-ins: their identified outputs are 2.0 V and 2.5 V, not 2.3 V. Also do not rely on distributor availability to override the verified not-for-new-designs status. Obtain the official pinout, exposed-pad connection, enable polarity, and capacitor values before attempting any replacement or board revision.
合規資訊
The supplied verified results do not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. Compliance must be confirmed from Semtech documentation or the current manufacturer product record.
