GENERAL DESCRIPTION

The ADP122/ADP123 are low quiescent current, low dropout linear regulators. They are designed to operate from an input voltage between 2.3 V and 5.5 V and to provide up to 300 mA of output current. The low 85 mV dropout voltage at a 300 mA load improves efficiency and allows operation over a wide input voltage range.

FEATURES

Input voltage supply range: 2.3 V to 5.5 V

300 mA maximum output current

Fixed and adjustable output voltage versions

Very low dropout voltage: 85 mV at 300 mA load

Low quiescent current: 45 µA at no load

Low shutdown current: <1 µA

Initial accuracy: ±1 accuracy

Up to 31 fixed-output voltage options available from 1.75 V to 3.3 V

Adjustable-output voltage range 0.8 V to 5.0 V (ADP123)

Excellent PSRR performance: 60 dB at 100 kHz

Excellent load/line transient response

Optimized for small 1.0 μF ceramic capacitors

Current limit and thermal overload protection

Logic controlled enable

Compact packages: 5-lead TSOT and 6-lead 2 mm × 2 mm LFCSP
