GENERAL DESCRIPTION
The ADP3330 is a member of the ADP330x family of precision
low dropout anyCAP voltage regulators. 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 con-
ventional 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 capaci-
tor, 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.
The SOT-23-6 package has been thermally enhanced using
Analog Devices’ proprietary Chip-on-Lead feature to maximize
power dissipation.
