GENERAL DESCRIPTION

The ADP3338 is a member of the ADP33xx family of precision,
low dropout, anyCAP voltage regulators. The ADP3338 operates
with an input voltage range of 2.7 V to 8 V and delivers a load
current up to 1 A. The ADP3338 stands out from conventional
LDOs with a novel architecture and an enhanced process that
allows it to offer performance advantages and higher output
current than its competition. Its patented design requires only a
1 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 ADP3338 achieves
exceptional accuracy of ±0.8% at room temperature and ±1.4%
over temperature, line, and load variations. The dropout voltage
of the ADP3338 is only 190 mV (typical) at 1 A. The device also
includes a safety current limit and thermal overload protection.
The ADP3338 has ultralow quiescent current: 110 µA (typical)
in light load situations.

1All limits at temperature extremes are guaranteed via correlation using standard statistical quality control (SQC) methods. Application stable with no load.
3VIN = 2.7 V for models with VOUTNOM ≤ 2.2 V.
ABSOLUTE MAXIMUM RATINGS
Unless otherwise specified, all voltages are referenced to GND.
Table 2.

Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those listed in the operational sections
of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability. Only one absolute maximum rating may be
applied at any one time.
ESD 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 this product 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.
