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.
