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.
