Fixed 3.3 V rail, 200 mA capacity
It takes an input up to 5.5 V and drops out 0.27 V max at 150 mA. Quiescent current sits at 50 µA, which keeps the part in the conversation for always-on or battery-backed rails where every microamp matters. The enable pin lets a system-level supervisor gate the output without an external pass FET. Protection covers over-current, over-temperature, short-circuit, and reverse polarity — the usual set for a modern LDO, but reverse-polarity protection is a welcome inclusion for field wiring where input polarity isn't guaranteed.
The part comes in a 4-X2SON package measuring 1x1 mm with an exposed pad.
The wide temp span also covers cold-crank conditions and hot-soak scenarios without derating the output current.
