ISL9000IRJCZ-T

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

The ISL9000IRJCZ-T is a dual low dropout linear regulator from the ISL9000A series, manufactured by Renesas Electronics (formerly Intersil). It features two independent fixed-output channels housed in a 10-lead DFN package measuring 3x3 mm. The device supports an input voltage range of 2.3 V to 6.5 V and delivers up to 3 A output current per channel. Key electrical specifications include a typical dropout voltage of 200 mV at 300 mA, load regulation of 0.1%, and voltage accuracy of 0.8%. It operates within a temperature range of -40°C to +85°C and integrates individual Power-On-Reset functions for each output.
