GENERAL DESCRIPTION
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 minimum output capacitor of
0.47 µF 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 an ultralow
ground current 34 µA (typical) in light load situations.
The 6-lead SOT-23 package has been thermally enhanced using
Analog Devices proprietary chip-on-lead feature to maximize
power dissipation.
