ISL9011AIRNJZ-T

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

The ISL9011AIRNJZ-T is a dual low-dropout (LDO) linear voltage regulator manufactured by Renesas Electronics Corporation. It features two independent output channels capable of sourcing up to 150 mA and 300 mA respectively. The device operates with an input voltage range of 2.3 V to 6.5 V and provides fixed output voltages, such as 2.8 V and 3.3 V. Key electrical specifications include a typical dropout voltage of 250 mV at 300 mA, a noise level of 30 μVRMS from 10 Hz to 100 kHz, and a quiescent current of approximately 40 μA. It utilizes a 10-lead DFN package measuring 3.0 mm x 3.0 mm.
