ISL9011AIRJNZ-T

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

The ISL9011AIRJNZ-T is a dual low-dropout (LDO) linear regulator manufactured by Renesas Electronics Corporation. It features two positive, fixed-voltage outputs housed in a 10-lead DFN package measuring 3x3 mm. The device supports an input voltage range from 2.3 V to 6.5 V. Output currents are rated at 150 mA for the first channel and 300 mA for the second channel. Fixed output voltages include combinations such as 2.8 V/1.8 V, 2.8 V/3.3 V, or 2.9 V/2.9 V. Key electrical parameters include a maximum dropout voltage of 0.2 V at 150 mA and a typical quiescent current of 40 µA.
