MinebeaMitsumi's linear regulators (LDOs) are developing distinctive products that take advantage of the strengths of CMOS processes and bipolar processes. Supports output current from 100mA to 1.5A, and in addition to functions including soft start, backflow protection, and auto discharge, we also have a lineup of products with special functions such as output current detection and temperature sensor output to meet customers needs.

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.
