GENERAL DESCRIPTION
The ADP172 is a low voltage input, low quiescent current, low-
dropout (LDO) linear regulator that operates from 1.6 V to 3.6 V
and provides up to 300 mA of output current. The low 50 mV
dropout voltage at 300 mA load improves efficiency and allows
operation over a wide input voltage range. The low 23 μA of
quiescent current at no load makes the ADP172 ideal for
battery-operated portable equipment.
The ADP172 is capable of 31 fixed-output voltage options, ranging
from 0.8 V to 3.0 V. The ADP172 is optimized for stable operation
with small 1 μF ceramic output capacitors. Ideal for powering
digital processors, the ADP172 exhibits good transient perform-
ance and occupies minimal board space. Compared with

commodity-type LDOs, the ADP172 provides 20 dB to 40 dB
better power supply rejection ratio (PSRR) at 100 kHz, making the
ADP172 an ideal power source for analog-to-digital converter
(ADC) mixed-signal processor systems and allowing use of
smaller size bypass capacitors. In addition, low output noise
performance without the need for an additional bypass capacitor
further reduces printed circuit board (PCB) component count.
Short-circuit protection and thermal overload protection circuits
prevent damage in adverse conditions. The ADP172 is available
in a tiny 4-ball, 0.5 mm pitch WLCSP for the smallest footprint
solution to meet a variety of portable power applications.
