GENERAL DESCRIPTION

The ADP3336 is a member of the ADP333x family of precision
low dropout anyCAP voltage regulators. The ADP3336 operates
with an input voltage range of 2.6 V to 12 V and delivers a
continuous load current up to 500 mA. The ADP3336 stands
out from conventional LDOs with the lowest thermal resistance
of any MSOP-8 package and an enhanced process that enables
it to offer performance advantages beyond 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 space­restricted applications. The ADP3336 achieves exceptional
accuracy of ±0.9% at room temperature and ±1.8% over tem­perature, line, and load. The dropout voltage of the ADP3336 is
only 200 mV (typical) at 500 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 ADP3336 has ultralow quiescent current
80 µA (typical) in light load situations.

CAUTION

ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection. Although
the ADP3336 features proprietary ESD protection circuitry, permanent damage may occur on
devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are
recommended to avoid performance degradation or loss of functionality.
