Adjustable LDO with 0.22 V max dropout at 50 mA
The LP2980IM5-ADJ is a single-output positive adjustable LDO from Texas Instruments, delivering up to 50 mA with a maximum dropout voltage of 0.22 V at full load. That dropout figure means the input rail can sit as low as 1.45 V above the set output voltage and still regulate — useful in battery-powered or post-switcher rails where headroom is tight.
PSRR and output range — what they buy the design
PSRR is 63 dB at 1 kHz, giving this LDO decent rejection of switching-regulator ripple in the audio band. Quiescent current is 95 µA typical, rising to 1.2 mA max under load — low enough for always-on domains in portable gear.
Industrial temp grade and protection set
On-chip protection includes over-current, over-temperature, and short-circuit — no external crowbar needed. The enable pin lets a system supervisor gate the output for sequencing.
NRND — sourcing reality for this LDO
That means it is still available for existing BOM lines but not the first choice for a fresh board spin.
