GENERAL DESCRIPTION

The ADP3335 is a member of the ADP333x family of precision,

low dropout, anyCAP voltage regulators. It operates with an

input voltage range of 2.6 V to 12 V, and delivers a continuous

load current up to 500 mA. The ADP3335 stands out from

conventional low dropout regulators (LDOs) by using an

enhanced process enabling 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 ADP3335 achieves

exceptional accuracy of ±0.9% at room temperature and ±1.8%

over temperature, line, and load.

The dropout voltage of the ADP3335 is only 200 mV (typical) at

500 mA. This device also includes a safety current limit, thermal

overload protection, and a shutdown feature. In shutdown

mode, the ground current is reduced to less than 1 µA. The

ADP3335 has a low quiescent current of 80 µA (typical) in light

load situations.
