ISL9000AIRFDZ-T

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

The ISL9000AIRFDZ-T is a dual-output low-dropout (LDO) voltage regulator manufactured by Renesas Electronics Corporation. It features two positive fixed output voltages of 2V and 2.5V, each capable of delivering up to 300mA of output current. The device 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 2V output and 0.5V at 300mA for the 2.5V output. Quiescent current is specified at 32µA, with a maximum supply current of 52µA. The regulator provides protection against overcurrent, thermal overload, and under-voltage lockout (UVLO), and includes enable and power-on reset control features.
