ISL9000IRBJZ-T

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

The ISL9000IRBJZ-T is a dual-output low-dropout (LDO) linear regulator from the ISL9000A series, manufactured by Renesas Electronics. It provides fixed positive output voltages of 1.5 V and 2.8 V with a maximum continuous output current of 300 mA 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 400 mV at 300 mA load. It includes integrated protection mechanisms such as overcurrent limiting, thermal shutdown, and under-voltage lockout (UVLO). The component is housed in a compact 10-lead DFN (3x3 mm) package with an exposed pad for thermal dissipation.
