Low-dropout CMOS linear regulator supplies up to 200 mA from a 2.2 V to 5.5 V input range. Fixed output-voltage options cover low-voltage rails with typical dropout of 140 mV at 200 mA. The regulator provides low output noise, high power-supply rejection, and low quiescent current for battery-powered and noise-sensitive circuits. Enable control supports shutdown operation, and the device is specified for operation from -40 °C to 125 °C. Package options include compact TSOT and WLCSP formats.
