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.
