Datasheet
This document describes the features and characteristics of the ADP121 CMOS linear regulator. The regulator has a wide input voltage range, adjustable output voltage range, high output current, and low quiescent current. It is suitable for applications such as mobile phones, digital cameras, audio devices, portable and battery-powered equipment.
Datasheet
The ADP121 is a low quiescent current, CMOS linear regulator that is available in a 5-lead TSOT or 4-ball 0.4 mm pitch WLCSP package. It offers input voltage range of 2.3 V to 5.5 V, output voltage range of 1.2 V to 3.3 V, output current of 150 mA, low quiescent current (IGND = 11 μA, no load; IGND = 30 μA, 150 mA load), low shutdown current (<1 μA), low dropout voltage (90 mV @ 150 mA load), high PSRR (70 dB @ 1 kHz at VOUT = 1.2 V; 70 dB @ 10 kHz at VOUT = 1.2 V), low noise (40 μV rms at VOUT = 1.2 V), no noise bypass capacitor required, output voltage accuracy of ±1%, 16 fixed output voltage options, current limit and thermal overload protection, logic controlled enable, and 5-lead TSOT or 4-ball 0.4 mm pitch WLCSP package.
