ISL9000IRFJZ

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

The ISL9000IRFJZ is a dual low-dropout linear regulator manufactured by Renesas Electronics Corporation. It provides two independent positive fixed output channels with a maximum current of 300mA per channel. The device operates within an input voltage range of 2.3V to 6.5V and offers fixed output voltages of 2.8V and 3.3V. Key electrical parameters include a maximum dropout voltage of 0.4V at 300mA, a quiescent current of 32µA, and a maximum supply current of 52µA. It features integrated protection mechanisms including overcurrent, thermal shutdown, and under-voltage lockout (UVLO), along with individual Power-On Reset (POR) functions for each output.
