ISL9014AIRNFZ

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The ISL9014AIRNFZ is a dual low-dropout linear regulator manufactured by Renesas Electronics Corporation. It integrates two independent LDOs within a single 10-lead DFN package measuring 3x3 mm. Each output channel provides a fixed voltage of 3.3V and 2.5V respectively, with a maximum continuous output current of 300mA per channel. The device operates from an input voltage range of 2.3V to 6.5V. Key electrical specifications include a maximum dropout voltage of 0.2V at 150mA load and 0.4V at 300mA load. The quiescent current is specified at 40 µA, with a maximum supply current of 60 µA.
