ISL9011AIRKKZ

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

The ISL9011AIRKKZ is a dual low-dropout (LDO) linear voltage regulator manufactured by Renesas Electronics. It operates within an input voltage range of 2.3 V to 6.5 V and provides two fixed output voltages, typically 2.8 V and 2.85 V. The device supports a maximum output current of 150 mA per channel. It features a low quiescent current of approximately 45 µA and includes an enable/shutdown pin for power management. The component is housed in a compact 10-lead DFN package measuring 3 mm x 3 mm with a 0.5 mm pitch.
