ISL9011AIRNNZ-T

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

The ISL9011AIRNNZ-T is a dual low-dropout (LDO) linear voltage regulator manufactured by Renesas Electronics Corporation. It features two independent output channels with fixed voltage settings, delivering up to 150 mA on the first channel and 300 mA on the second. The device operates within an input voltage range of 2.3 V to 6.5 V and maintains a typical dropout voltage of 250 mV at full load. It incorporates a 30 μVrms noise profile across the 10 Hz to 100 kHz bandwidth and provides high power supply rejection ratio performance. The component is housed in a compact 10-lead DFN package measuring 3.0 mm x 3.0 mm.
