ISL9000IRJRZ

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

The ISL9000IRJRZ is a dual-output linear voltage regulator manufactured by Renesas Electronics Corporation. It provides fixed positive output voltages of 2.6V and 2.8V, with each channel capable of delivering up to 300mA. The device operates within an input voltage range of up to 6.5V and features a typical dropout voltage of 250mV at full load. Key electrical characteristics include a quiescent current of 32µA and a maximum supply current of 52µA. It is housed in a compact 10-DFN (3x3) package with an exposed pad for thermal management.
