It comes in a 5-pin SOT-23-5 package and operates across the full -40°C to 125°C temperature range. Key features include a low 95 µA quiescent current, a maximum dropout voltage of 0.85 V at full load, and a PSRR of 45 dB at 1 kHz. Built-in protection covers over-current, over-temperature, and short-circuit events, with an enable pin for on/off control. This part is suited for powering analog front-ends, low-power MCUs, and sensor rails in industrial, automotive, and battery-operated equipment where a clean, stable 2.5 V supply is needed. ## Quiescent current and enable — always-on and duty-cycled designs At 95 µA quiescent current, this regulator draws very little just to stay alive — useful for battery-powered equipment that spends most of its time in a low-power state. The enable pin lets a system controller shut down the output completely, dropping the supply current to near zero. That combination makes it a good fit for IoT edge nodes, portable instruments, and automotive body modules that need to wake on a signal. ## Package and mounting — SOT-23-5 footprint The SOT-23-5 surface-mount package is a standard small outline with five leads. Board layout uses a single ground plane under the device for thermal dissipation; the 250 mA output at high ambient temperature benefits from adequate copper area. The enable pin is active-high — leave it floating or tie to input if not used. ## Lifecycle and compliance It is ROHS3 compliant.","metaTitle":"LP2992IM5-2.5/NOPB LDO Regulator, 2.5V Fixed Output, 250mA","metaDescription":"Texas Instruments LP2992IM5-2.5/NOPB is a fixed 2.5V LDO linear regulator delivering 250mA. 45dB PSRR at 1kHz, 95µA quiescent current, -40°C to 125°C range.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"PSRR":"45dB (1kHz)","Package":"Tape & Reel (TR); Cut Tape (CT)","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"SC-74A, SOT-753","lifecycle_stage":"eol_hot","Control Features":"Enable","Current - Output":"250mA","Protection Features":"Over Current, Over Temperature, Short Circuit","Number of Regulators":"1","Output Configuration":"Positive","Operating Temperature":"-40°C ~ 125°C","Voltage - Input (Max)":"16V","Voltage Dropout (Max)":"0.85V @ 250mA","Current - Supply (Max)":"4 mA","Supplier Device Package":"SOT-23-5","Current - Quiescent (Iq)":"95 µA","Voltage - Output (Min/Fixed)":"2.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.7","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.70000","currency":"USD"},{"qty":10,"price":"$1.51700","currency":"USD"},{"qty":25,"price":"$1.43960","currency":"USD"},{"qty":100,"price":"$1.18240","currency":"USD"},{"qty":250,"price":"$1.10532","currency":"USD"},{"qty":500,"price":"$0.97680","currency":"USD"},{"qty":1000,"price":"$0.77115","currency":"USD"},{"qty":2000,"price":"$0.72750","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/7521c37bf426e643a6074eb96e4d21ec.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What are the alternatives for LP2992IM5-2.5/NOPB?","answer":"Within the LP2992 family, other fixed-output voltage variants (e.g., 1.8 V, 3.3 V) share the same pinout and package. For a different dropout or current rating, consider the LP2985 or LP38690 series, but verify pin compatibility and thermal performance for your load."},{"question":"What is LP2992IM5-2.5/NOPB's PSRR?","answer":"PSRR is 45 dB at 1 kHz.
