ISL9000AIRNNZ-T

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

The ISL9000AIRNNZ-T is a dual-channel low-dropout linear regulator from the Renesas ISL9000A series, housed in a 10-lead DFN (3x3 mm) surface-mount package. It integrates two independent positive fixed-output regulators delivering up to 3 A per channel. The device operates with an input voltage range of 2.3 V to 6.5 V and provides fixed output voltages of 3.3 V on both channels. Key electrical specifications include a maximum dropout voltage of 0.325 V at 300 mA load, a reference voltage of 1 V, and a voltage regulation accuracy of 0.8%. It features a load regulation of 0.1% and supports operation within a temperature range of -40°C to +85°C.
