ISL9000AIRKKZ

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

The ISL9000AIRKKZ is a dual-channel low-dropout linear regulator manufactured by Renesas Electronics Corporation. It provides two independent positive fixed outputs, specifically configured for 2.85V per channel in this variant. The device supports a continuous output current of 300mA per channel and operates within an input voltage range up to 6.5V. Key electrical parameters include a maximum dropout voltage of 0.325V at full load and a typical quiescent current of 32µA. It features integrated protection mechanisms including overcurrent, thermal shutdown, and undervoltage lockout.
