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, V_IN,

from which the output is powered.

The ADP3342 stands out from the conventional LDOs with the

lowest thermal resistance of any MSOP-8 package and an enhanced

process that enables it to offer performance advantages beyond

its competition. Its patented design requires only a 1.0 µF output

capacitor for stability. This device is insensitive to output capacitor

Equivalent Series Resistance (ESR), and is stable with any good

quality capacitor, including ceramic (MLCC) types for space-

restricted applications. The dropout voltage of the ADP3342 is

only 190 mV (typical) at 300 mA. This device also includes a

safety current limit, thermal overload protection and a shutdown

control pin.
