What this 1A adjustable LDO brings to the rail
PSRR runs 48 dB at 100 Hz and holds at 38 dB through 1 MHz, which puts it in the class of LDOs that can clean up a switching preregulator's ripple without needing a post-filter stage. The 100 µA quiescent current (350 µA max supply) keeps the overhead low for always-on rails in battery-backed or standby domains.
Protection features for field-deployed rails
Reverse polarity protection is uncommon on LDOs at this current level — it clamps the pass element so a reversed battery connection doesn't dump current through the substrate. The UVLO holds the output off until the input rises above the internal threshold, preventing the load from seeing a brown-out voltage during startup or sag. Over-current and thermal shutdown handle the rest: foldback limits the current, and the die shuts down if the junction hits the thermal limit.
