ISL9000AIRKFZ

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

The ISL9000AIRKFZ is a dual-channel low-dropout linear regulator manufactured by Renesas Electronics Corporation. It integrates two independent positive fixed-output LDOs within a single 10-lead VFDFN package measuring 3.00 x 3.00 mm with a height of 0.88 mm. The device provides fixed output voltages of 2.5V and 2.85V, each capable of delivering up to 300mA of output current. It operates with an input voltage range from 2.3V to 6.5V. Key electrical parameters include a maximum dropout voltage of 0.4V at 300mA for the first channel and 0.325V at 300mA for the second channel. The quiescent current is specified at 32µA, with a maximum supply current of 52µA. The component supports an operating temperature range of -40°C to +85°C.
