ISL9011IRPLZ

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

The ISL9011IRPLZ is a dual low-dropout (LDO) voltage regulator manufactured by Intersil, now part of Renesas. It features two independent channels capable of sourcing 150mA from Channel 1 and 300mA from Channel 2. The device operates with an input voltage range of 2.3V to 6.5V and maintains stability with output capacitance between 1µF and 10µF having an ESR up to 200mΩ. It offers a typical quiescent current of 45µA when both LDOs are active.
