MIC5330-GGYML-TR

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

The MIC5330-GGYML-TR is a dual ultra-low dropout linear regulator featuring two independent 300mA LDOs within an 8-pin 2mm x 2mm MLF package. It operates with an input voltage range of 2.3V to 5.5V and provides fixed output voltages of 1.8V for both channels. The device exhibits high power supply rejection exceeding 70dB at 1kHz, ultra-low output noise of 30µVRMS, and ±2% initial output accuracy. It includes thermal shutdown and current limit protection, with a low quiescent current of 75µA per output.
