This document describes the features and characteristics of the ADP151 ultralow noise, 200mA, CMOS linear regulator, including ultralow noise of 9uVrms, stability with 1uF ceramic input and output capacitors, maximum output current of 200mA, input voltage range of 2.2V to 5.5V, low quiescent current and shutdown current, low dropout voltage, 16 fixed output voltage options, etc.
The ADP151 linear regulator from Analog Devices provides up to 200 mA of output current with ultralow noise (9 pV rms) and no external bypass capacitor required. It operates from 2.2 V to 5.5 V input and offers 16 fixed output voltage options from 1.1 V to 3.3 V.
Typical applications include RF, VCO, PLL power supplies, mobile phones, digital cameras, portable battery‑powered equipment, and medical devices. The device is available in compact 5‑lead TSOT, 6‑lead LFCSP, and 4‑ball WLCSP packages and includes built‑in current‑limit and thermal‑overload protection.
