Linear regulator (LDO)

MM1998

Overview

This IC is a negative output 200mA LDO with fast turn-on by bipolar process.
The target applications are a negative power supply for highly sensitive CMOS image sensor by low noise design. And The IC has the line-up of output voltage -5.0V to -1.1V (0.1V steps) by the specifications of image sensor.
The package can be selected from SOT-25/SSON-6A for low cost or small space of PCB.

Application

・Photographing / Imaging device
・Power supply for high-sensitivity image sensor
・Power supply for negative voltage circuit
