ADP122AUJZ-2.8-R7 5.5 V Input, 300 mA, Low Quiescent Current, CMOS Linear Regulator

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.
The low 170 μA of quiescent current at full load makes the ADP122 ideal for battery-operated portable equipment.

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, 5-lead TSOT package

APPLICATIONS
Digital camera and audio devices
Portable and battery-powered equipment
Automatic meter reading (AMR) meters
GPS and location management units
Medical instrumentation
Point-of-sale equipment
