ISL9011AIRLLZ-T

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

The ISL9011AIRLLZ-T is a dual low-dropout linear regulator manufactured by Renesas Electronics Corporation. It integrates two independent LDO channels within a single 10-lead, 3mm x 3mm DFN package. Channel 1 provides a fixed output voltage of 2.9V with a maximum continuous current capability of 150mA. Channel 2 also delivers a fixed output voltage of 2.9V, supporting up to 300mA of continuous load current. The device operates from an input supply voltage ranging between 2.3V and 6.5V. It features a typical quiescent current of 45µA when both regulators are active and draws less than 0.1µA in shutdown mode. The unit includes separate enable pins for each channel, soft-start functionality, and thermal protection.
