Overview
The ADP3339AKCZ-5-R7 is a high-accuracy, ultralow quiescent current (IQ), anyCAP low dropout regulator (LDO) produced by Analog Devices Inc. This device is part of the ADP33xx family of precision LDOs and stands out due to its novel architecture and enhanced process, offering superior performance and higher output current compared to conventional LDOs.
It operates with an input voltage range of 2.8V to 6V and delivers a load current up to 1.5A. The ADP3339AKCZ-5-R7 is notable for its high accuracy over line and load, with a tolerance of ±0.9% at 25°C and ±1.5% over temperature. It also features an ultralow dropout voltage of 230mV (typical) at 1.5A and requires only a 1μF output capacitor for stability, making it suitable for space-restricted applications.
