ISL9000AIRNCZ

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

The ISL9000AIRNCZ is a dual low-dropout linear regulator manufactured by Renesas Electronics Corporation. It provides two fixed positive output voltages of 1.8V and 3.3V, each capable of sourcing up to 300mA. The device operates with an input voltage range from 2.3V to 6.5V. Key electrical parameters include a maximum quiescent current of 52µA and a typical static current of 32µA. Power supply rejection ratio (PSRR) ranges from 90dB at 1kHz to 50dB at 100kHz. The maximum dropout voltage is specified as 0.4V at 300mA load. It is housed in a 10-DFN (3x3mm) package with exposed pad.
