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 V BIAS
supply powers the part, and the lower V IN 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 fixed output voltages ranging from :
0.80 V to 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.
