ISL9000AIRJCZ

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

The ISL9000AIRJCZ is a dual low dropout (LDO) voltage regulator from the ISL9000A series, manufactured by Renesas/Intersil. It provides two fixed output voltages of 1.5V and 2.8V with a combined maximum output current of 3A per channel. The device operates within an input voltage range of 2.3V to 6.5V and features a typical dropout voltage of 0.3V at 300mA load. It maintains a voltage regulation accuracy of 0.8% and includes integrated Power-On-Reset (POR) functions for each output. The component is housed in a DFN-10 package and supports operation temperatures from -40°C to +85°C.
