ISL9000AIRKJZ

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

The ISL9000AIRKJZ is a dual low-dropout linear regulator from the ISL9000A series, manufactured by Renesas Electronics. It provides two fixed output voltages of 2.8 V and 2.85 V with a maximum output current of 3 A per channel. The device operates within an input voltage range of 2.3 V to 6.5 V and features a typical dropout voltage of 200 mV at full load. It is housed in a 10-lead DFN-10 (3x3 mm) surface-mount package. The component supports a positive polarity configuration and maintains operation across a temperature range of -40°C to +85°C.
