ISL9000AIRKCZ

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

The ISL9000AIRKCZ is a dual low-dropout linear regulator manufactured by Renesas Electronics Corporation. It provides two independent positive fixed output channels with voltages of 1.8V and 2.85V, 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 0.325V at full load. It utilizes a 10-pin VFDFN package measuring 3.00 x 3.00mm with a height of 0.88mm. Key electrical parameters include a quiescent current of 32µA and a supply current of 52µA. The unit supports an operating temperature range from -40°C to +85°C.
