GENERAL DESCRIPTION

The ADP3339 is a member of the ADP33xx family of precision, low dropout, anyCAP® voltage regulators. The ADP3339 operates with an input voltage range of 2.8 V to 6 V and delivers a load current up to 1.5 A. The ADP3339 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 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 space-restricted applications. The ADP3339 achieves exceptional accuracy of ±0.9% at room temperature and ±1.5% over temperature, line, and load variations. The dropout voltage of the ADP3339 is only 230 mV (typical) at 1.5 A. The device also includes a safety current limit and thermal overload protection. The ADP3339 has ultralow quiescent current: 130 μA (typical) in light load situations.

ABSOLUTE MAXIMUM RATINGS Unless otherwise specified, all voltages are referenced to GND.

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.
