ISL9011IRKJZ-T

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

The ISL9011IRKJZ-T is a dual low-dropout linear regulator manufactured by Renesas Electronics Corporation. It integrates two independent LDO channels within a compact 10-lead, 3mm x 3mm Dual Flat No-Lead (DFN) package. Channel 1 provides a fixed output voltage of 2.85V with a maximum continuous current capability of 150mA. Channel 2 delivers a fixed output voltage of 2.8V with a maximum continuous current capability of 300mA. 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 channels are active and includes separate enable pins for individual channel control.
