Quiescent current is 95 µA typical, keeping the always-on power budget low for battery-operated or standby circuits. Built-in over-current, over-temperature, and short-circuit protection let the regulator survive a momentary output short without external clamp diodes. An Enable pin gives the system designer a way to sequence the rail on/off or shut down the LDO in sleep mode.","metaTitle":"LP2980AIM5-4.0/NOPB LDO Regulator, 4.0V Fixed, 50mA","metaDescription":"Texas Instruments LP2980AIM5-4.0/NOPB is a 50mA fixed-output LDO with 63dB PSRR at 1kHz, 95µA Iq, and -40°C to 125°C range.","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); Cut Tape (CT)","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)":"4V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/eabcfdbdb17bcf38ee7ef2c6d535c154.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LP2980AIM5-4.0%2FNOPB/alternatives.json"},"ai":{"faq":[{"question":"What is a replacement for LP2980AIM5-4.0/NOPB?","answer":"No official replacement or pin-compatible cross-reference is documented by Texas Instruments for this exact fixed 4.0 V output in the SOT-23-5 package.
