ISL9011AIRKJZ

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

The ISL9011AIRKJZ is a dual low-dropout linear regulator from the ISL9011A series, manufactured by Renesas Electronics. It features two independent channels with fixed output voltages of 2.8 V and 2.85 V. The device supports an input voltage range from 2.3 V to 6.5 V. Channel 1 provides a maximum output current of 150 mA, while Channel 2 delivers up to 300 mA. Key electrical specifications include a typical dropout voltage of 250 mV at 150 mA and a maximum of 400 mV. The quiescent current is typically 45 µA with both channels active. The unit operates within a temperature range of -40°C to +85°C and is housed in a DFN-10 package.
