ISL9000IRJRZ-T

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

The ISL9000IRJRZ-T is a dual low-dropout (LDO) linear regulator manufactured by Renesas Electronics Corporation. It integrates two independent high-performance LDOs within a single 10-lead DFN package. Each output channel provides a fixed voltage of 2.8V and 3.3V respectively, with a maximum continuous output current of 300mA per channel. The device operates from an input voltage range of 2.3V to 6.5V. Key electrical specifications include a typical quiescent current of 42µA when both LDOs are active, a dropout voltage of approximately 0.325V at 300mA for the first output and 0.4V for the second. It features ±1.8% accuracy over operating conditions and includes integrated power-on-reset functions.
