ISL9011AIRJNZ

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

The ISL9011AIRJNZ is a dual low-dropout (LDO) linear regulator manufactured by Renesas Electronics Corporation. It features two independent positive fixed outputs with maximum current ratings of 300mA each. The device operates within an input voltage range of 2.3V to 6.5V and provides fixed output voltages of 2.8V and 3.3V. It utilizes a 10-lead DFN package measuring 3mm x 3mm. Key electrical characteristics include a typical dropout voltage of 250mV at 300mA, a quiescent current of 40µA, and noise performance of 30µVRMS from 10Hz to 100kHz.
