GENERAL DESCRIPTION
The ADP121 is a quiescent current, low dropout, linear regulators
that operate from 2.3 V to 5.5 V and provide up to 150 mA of
output current. The low 135 mV dropout voltage at 150 mA
load improves efficiency and allows operation over a wide
input voltage range. The low 30 μA of quiescent current at full
load make the ADP121 ideal for battery-operated portable
equipment.
The ADP121 is available in 16 fixed output voltage options
ranging from 1.2 V to 3.3 V. The parts are optimized for stable

operation with small 1 μF ceramic output capacitors. The
ADP121 delivers good transient performance with minimal
board area.
Short-circuit protection and thermal overload protection circuits
prevent damage in adverse conditions. The ADP121 is available
in a tiny 5-lead TSOT and 4-ball 0.4 mm pitch WLCSP pack-
ages and utilizes the smallest footprint solution to meet a
variety of portable applications.
