Its 63 dB PSRR at 1 kHz knocks down switching-regulator ripple before it reaches a VCO, ADC reference, or sensor bias circuit. The 95 µA quiescent current keeps the battery drain low in always-on subsystems. ## Adjustable output from 1.23 V to 15 V — one part, multiple rails The output is adjustable via two external resistors from a 1.23 V reference up to 15 V. The 16 V maximum input gives headroom for 12 V intermediate buses. ## Industrial temperature range and protection set On-chip protection includes over-current, over-temperature, and short-circuit — no external crowbar or foldback circuit needed. The enable pin lets a microcontroller gate the rail for sequenced power-up or sleep-mode power-down. ## SOT-23-5 footprint and sourcing posture The LP2980IM5-ADJ/NOPB comes in a 5-pin SOT-23-5 (SC-74A) package, surface-mount for automated assembly.","metaTitle":"LP2980IM5-ADJ/NOPB Texas Instruments LDO, 50mA Adjustable","metaDescription":"Texas Instruments LP2980IM5-ADJ/NOPB adjustable LDO regulator, 50 mA output, 63 dB PSRR at 1 kHz, -40°C to 125°C.
