GENERAL DESCRIPTION

The ADP3333 is a member of the ADP333x family of precision

low dropout (LDO) anyCAP® voltage regulators. Pin compatible

with the MAX8860, the ADP3333 operates with a wider input

voltage range of 2.6 V to 12 V and delivers a load current up to

300 mA. ADP3333 stands out from other conventional LDOs

with a novel architecture and an enhanced process that enables

it to offer performance advantages over 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 ADP3333 achieves exceptional accuracy of

0.8% at room temperature and 1.8% over temperature, line,

and load variations. The dropout voltage of the ADP3333 is

only 140 mV (typical) at 300 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 ADP3333 has ultralow quiescent current,

70 μA (typical) in light load situations.
