GENERAL DESCRIPTION
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

with any good quality capacitor, including ceramic (MLCC)
types for space-restricted applications. The ADP3338 achieves
exceptional accuracy of ±0.8% at room temperature and ±1.4%
over temperature, line, and load variations. The dropout voltage
of the ADP3338 is only 190 mV (typical) at 1 A. The device also
includes a safety current limit and thermal overload protection.
The ADP3338 has ultralow quiescent current: 110 μA (typical)
in light load situations.
