ISL9014AIRMMZ

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

The ISL9014AIRMMZ is a dual low-dropout (LDO) linear regulator manufactured by Renesas Electronics Corporation. It provides two fixed positive output voltages of 3.0V on both VO1 and VO2, each capable of sourcing up to 300mA. The device operates with an input voltage range of 2.3V to 6.5V and features extremely low quiescent current consumption of typically 45µA when both LDOs are active. It incorporates separate enable pins for individual control, soft-start functionality, and protection against overcurrent and overheating.
