GENERAL DESCRIPTION

The ADP130 is a low quiescent current, low dropout linear regulator. 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.

FEATURES

350 mA maximum output current

Input voltage supply range

VBIAS = 2.3 V to 5.5 V

VIN = 1.2 V to 3.6 V

2.3 V < VIN < 3.6 V, VIN can be tied to VBIAS

Very low dropout voltage: 17 mV @ 100 mA load

Low quiescent current: 25 μA @ no load

Low shutdown current: <1 μA

±1 accuracy @ 25°C

Excellent PSRR performance: 70 dB @ 10 kHz

Excellent load/line transient response

Optimized for small 1 μF ceramic capacitors

Current limit and thermal overload protection

Logic controlled enable

5-lead TSOT package

APPLICATIONS

Mobile phones

Digital camera and audio devices

Portable and battery-powered equipment

Post dc-to-dc regulation
