ISL9011IRLLZ

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

The ISL9011IRLLZ is a dual low-dropout linear regulator manufactured by Renesas Electronics Corporation. It provides two fixed positive output voltages of 2.9V each, housed in a 10-lead 3mm x 3mm DFN package. Channel 1 supports a continuous output current of 150mA, while Channel 2 supports 300mA. The device operates with an input voltage range from 2.3V to 6.5V and maintains a typical quiescent current of 45µA when both LDOs are active. Dropout voltage is typically 120mV at 150mA for the first channel.
