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 F 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 A. The
ADP3335 has a low quiescent current of 80 A (typical) in light
load situations.
