ISL9000AIRJBZ

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

The ISL9000AIRJBZ is a dual-output linear low-dropout (LDO) voltage regulator manufactured by Renesas Electronics Corporation. It provides fixed output voltages of 1.5V and 2.8V, with each channel capable of sourcing up to 300mA. The device operates within an input voltage range of 2.3V to 6.5V and features a maximum dropout voltage of 0.4V at full load. Key electrical specifications include a quiescent current of 32µA and a maximum supply current of 52µA. It is housed in a 10-DFN (3x3mm) package with an exposed pad, suitable for surface-mount installation across an operating temperature range of -40°C to +85°C.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary
