ISL9000AIRJCZ

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

The ISL9000AIRJCZ is a dual-channel low-dropout linear regulator manufactured by Renesas Electronics Corporation. It provides fixed output voltages of 1.8V and 2.8V, each 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. It utilizes a 10-pin VFDFN package with dimensions of 3.00mm x 3.00mm and a height of 0.88mm. Quiescent current is specified at 32µA, with a maximum supply current of 52µA. The component supports operation from -40°C to +85°C.
