GENERAL DESCRIPTION

with any good quality capacitor, including ceramic (MLCC)

The ADP3338 is a member of the ADP33xx family of precision,

low dropout (LDO), anyCAP voltage regulators. The ADP3338

operates with an input voltage range of 2.7 V to 8 V and delivers

a load current up to 1 A. The ADP3338 stands out from

conventional LDOs with a novel architecture and an enhanced

process that offers performance advantages and higher output

current than its competition. Its patented design requires only a

1 µF output capacitor for stability. This device is insensitive to

output capacitor equivalent series resistance (ESR), and is stable

types for space-restricted applications. The ADP3338 achieves

exceptional accuracy of ±±.8ꢀ at room temperature and ±1.ꢁꢀ

over temperature, line, and load variations. The dropout voltage

of the ADP3338 is only 19± mV (typical) at 1 A. The device also

includes a safety current limit and thermal overload protection.

The ADP3338 has ultralow quiescent current: 11± µA (typical)

in light load situations.
