GENERAL DESCRIPTION
The ADP130 is a low quiescent current, low dropout linear regu-
lator. It is designed to operate in dual-supply mode with an input
voltage as low as 1.2 V to increase efficiency and provide up to
350 mA of output current. The low 17 mV dropout voltage at
a 100 mA load improves efficiency and allows operation over
a wider input voltage range.
A dual-supply power solution typically improves conversion
efficiency over a single-supply solution because the higher VBIAS
supply powers the part, and the lower VIN supply delivers current
to the load. The power dissipated in the device is thereby reduced.
The ADP130 is optimized for stable operation with small 1 μF
ceramic output capacitors. The ADP130 delivers good transient
performance with minimal board area.

The ADP130 is available in the following 31 fixed output voltage
options:
0.80 V to 2.00 V in 50 mV steps
1.875 V, 2.25 V, 2.50 V, 2.775 V, 2.80 V, and 3.0 V
The ADP130 has a typical internal soft start time of 200 μs. Short-
circuit protection and thermal overload protection circuits
prevent damage in adverse conditions. The ADP130 is available
in a tiny 5-lead TSOT package for the smallest footprint solution to
meet a variety of portable power applications.
