The quiescent current sits at 95 µA typical, rising to 1.2 mA max under all conditions — low enough that the regulator does not eat into the load budget on a battery-powered or lightly loaded rail. Built-in protection covers over-current, over-temperature, and short-circuit events — the regulator folds back or shuts down rather than letting the pass element exceed its safe operating area. An Enable pin (active-high logic) lets the system designer gate the output rail for sequenced power-up or low-power sleep modes. The SOT-23-5 package (SC-74A, SOT-753) is a five-pin surface-mount footprint with a 0.95 mm pin pitch, common enough that the PCB layout and assembly profile are well understood across most contract manufacturers. That means the manufacturer has announced end-of-life and is accepting final orders within a defined window.","metaTitle":"LP2980IM5-5.0 LDO Regulator, 5V Fixed Output, 50mA, SOT-23-5","metaDescription":"LP2980IM5-5.0 from Texas Instruments: 5V fixed-output LDO, 50mA, 0.22V dropout, 63dB PSRR at 1kHz.

That level of ripple rejection cleans up a 5 V rail for analog loads — ADC references, op-amp supplies, sensor bias — where input ripple would otherwise couple into the signal path and degrade measurement accuracy."},{"question":"LP2980IM5-5.0 vs LP2980IM5-3.3: what is the difference?","answer":"The two parts share the same die, package (SOT-23-5), output current (50 mA), dropout voltage (0.22 V max), and protection features. The only difference is the fixed output voltage: the LP2980IM5-5.0 delivers 5 V, while the LP2980IM5-3.3 delivers 3.3 V. The pinout and footprint are identical, so a board designed for one can accept the other by changing the BOM line and verifying the downstream load voltage tolerance."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LP2980IM5-5.0","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LP2980IM5-5.0 when reusing this data.
