ISL9014AIRNNZ

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

The ISL9014AIRNNZ is a dual-output fixed positive linear regulator manufactured by Renesas Electronics Corporation. It provides two independent outputs of 3.3V each, with a maximum output current of 300mA per channel. The device operates within an input voltage range of 2.3V to 6.5V and features a typical quiescent current of 40µA. It utilizes a 10-DFN (3x3mm) surface-mount package with exposed pad. Protection mechanisms include overcurrent, thermal shutdown, soft start, and undervoltage lockout.
