ISL9011AIRNJZ

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

The ISL9011AIRNJZ 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 positive output voltages: 2.8 V and 3.3 V. The device delivers a maximum output current of 150 mA per channel with a typical dropout voltage of 250 mV at full load. It features a noise level of 30 μVRMS from 10 Hz to 100 kHz and offers high power supply rejection ratio (PSRR). The regulator includes enable/shutdown control, overcurrent protection, thermal shutdown, and soft-start functionality. It is housed in a 10-lead DFN package measuring 3.0 x 3.0 mm and operates across a temperature range of -40°C to +85°C.
