ISL9012IRMGZ

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

The ISL9012IRMGZ is a dual-output linear low-dropout (LDO) voltage regulator manufactured by Renesas Electronics Corporation. It integrates two independent positive fixed output regulators within a single 10-lead, 3x3 mm VFDFN package with an exposed pad. The device provides regulated outputs of 2.7V and 1.8V, supporting maximum continuous currents of 150mA and 300mA respectively. It operates from a single input supply voltage ranging up to 6.5V. Key electrical characteristics include a maximum dropout voltage of 0.2V at 150mA load, a typical quiescent current of 40µA, and a maximum supply current of 60µA. The unit features high power supply rejection ratio (PSRR) performance, specified as 70dB at 1kHz and 40dB at 100kHz.
