ISL9000IRMGZ-T

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

The ISL9000IRMGZ-T is a dual-output positive fixed linear voltage regulator (LDO) manufactured by Renesas Electronics. It provides two independent output channels, each capable of sourcing up to 300mA. The device features low standby current and very high Power Supply Rejection Ratio (PSRR). Key electrical parameters include a maximum input voltage of 6.5V and output voltages of 2.8V and 3V. Dropout voltages are specified at 0.4V @ 300mA and 0.325V @ 300mA for the respective outputs. Quiescent current is 32 µA, with maximum supply current of 52 µA. It operates within a temperature range of -40°C to 85°C.
