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.

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.
