GENERAL DESCRIPTION

The ADP121 is a quiescent current, low dropout, linear regulator

that operates from 2.3 V to 5.5 V and provides 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 makes the ADP121 ideal for battery-operated portable

equipment.

The ADP121 is available in output voltages 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 halide-free

WLCSP packages and utilizes the smallest footprint solution to

meet a variety of portable applications.
