The ADP3330 is a member of the Analog Devices, Inc., precision low dropout (LDO) anyCAP® voltage regulator family of products. The ADP3330 operates
with an input voltage range of +2.9 V to +12 V and delivers a
load current up to 200 mA. The ADP3330 stands out from the
conventional LDOs with a novel architecture and an enhanced
process that enables it to offer performance advantages and
higher output current than its competition. Its patented design
requires only a 0.47 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 ADP3330 achieves exceptional accuracy of
±0.7% at room temperature and ±1.4% over temperature, line
and load variations. The dropout voltage of the ADP3330 is
only 140 mV (typical) at 200 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 2 µA. The ADP3330 has ultralow quiescent current
34 µA (typ) in light load situations.
