ISL9011IRGPZ-T

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

The ISL9011IRGPZ-T is a dual low-dropout linear regulator manufactured by Renesas Electronics Corporation. It integrates two independent LDO channels within a 10-lead, 3mm x 3mm Dual Flat No-Lead (DFN) package. Channel 1 provides a fixed output voltage of 2.7V with a maximum continuous current capability of 150mA. Channel 2 delivers a fixed output voltage of 1.85V with a maximum continuous current capability of 300mA. The device operates over an input supply voltage range of 2.3V to 6.5V and supports an ambient operating temperature range from -40°C to +85°C.
