ISL9000AIRFCZ

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

The ISL9000AIRFCZ is a dual-channel low-dropout linear regulator manufactured by Renesas Electronics Corporation. It integrates two independent positive fixed-output LDOs within a compact 10-lead VFDFN package measuring 3x3 mm with a height of 0.88 mm. The device supports an input voltage range from 2.3 V to 6.5 V and provides fixed output voltages of 1.8 V and 2.5 V. Each channel delivers a maximum output current of 300 mA with a maximum dropout voltage of 0.4 V at full load. Quiescent current is specified at 32 µA, while maximum supply current reaches 52 µA. The component operates reliably across a temperature range of -40°C to +85°C.
