The SOT-23-5 footprint is a standard low-profile surface-mount package.
Maximum dropout is 0.58 V at the full 150 mA load. Quiescent current sits at 95 µA typical. The 16 V maximum input voltage lets this LDO survive load-dump transients. Over-current, over-temperature, and short-circuit protection are built in.
It is ROHS3 compliant.
