The ADP150 is an ultra-low noise, 150mA CMOS linear regulator with 9µVrms of ultra-low noise, 105mV dropout voltage, 150mA maximum output current, 2.2V to 5.5V input voltage range, and 1.8V to 3.3V fixed output voltage options.
The ADP150 linear regulator from Analog Devices provides ultralow noise (9 pV rms) and low quiescent current, making it suitable for battery‑powered and noise‑sensitive applications. It operates from 2.2 V to 5.5 V input and delivers up to 150 mA output current in a tiny 5‑lead TSOT or 4‑ball WLCSP package.
The datasheet includes detailed specifications, typical application circuits, thermal data, pin descriptions, and an ordering guide for the 14 fixed output‑voltage options ranging from 1.8 V to 3.3 V.
