GENERAL DESCRIPTION
The ADP3333 is a member of the ADP333x family of precision
low dropout (LDO) any CAP 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 (typ) in light load situations.
