Maximum dropout is 0.22 V at 50 mA. Quiescent current is 95 µA typical; maximum supply current is 1.2 mA. ## Industrial temperature grade and protection set The protection block includes over-current, over-temperature, and short-circuit — enough to survive a bench fault or a hot reflow without latching up. The enable control feature lets a GPIO or supervisor IC gate the output, which is useful for sequencing multiple rails or shutting down a peripheral in sleep mode. The fixed 3.2 V output is less common than 3.3 V — check that your load's tolerance band accepts the 3.2 V nominal before committing the BOM. Confirm the pinout against the datasheet before ordering replacement stock.","metaTitle":"LP2980IM5X-3.2/NOPB LDO Regulator, 50 mA, 3.2 V Fixed","metaDescription":"Texas Instruments LP2980IM5X-3.2/NOPB LDO voltage regulator, 50 mA output, 3.2 V fixed, 63 dB PSRR at 1 kHz, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","PSRR":"63dB (1kHz)","Series":"-","Package":"Tape & Reel (TR)","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"SC-74A, SOT-753","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Control Features":"Enable","Current - Output":"50mA","Base Product Number":"LP2980","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)":"0.22V @ 50mA","Current - Supply (Max)":"1.2 mA","Voltage - Output (Max)":"-","Supplier Device Package":"SOT-23-5","Current - Quiescent (Iq)":"95 µA","Voltage - Output (Min/Fixed)":"3.2V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/865be670b7e185d590e6565808fed4d6.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LP2980IM5X-3.2%2FNOPB/alternatives.json"},"ai":{"faq":[{"question":"Is LP2980IM5X-3.2/NOPB obsolete?","answer":"Yes, the LP2980IM5X-3.2/NOPB carries an obsolete lifecycle status.
