GENERAL DESCRIPTION

The ADP3342 is a unique member of the ADP330x family of precision low dropout anyCAP voltage regulators. The ADP3342 operates with an input voltage range of 1.7 V to 6 V and delivers a continuous load current up to 300 mA. In order to support the ability to regulate from such a low input voltage, the power rail to the IC, VCC, has been split off from the main power rail, VIN, from which the output is powered.
