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 low noise negative output 200mA LDO by bipolar process. The target applications by noise reduction pin are for a power supply of highly sensitive image sensor. The output range is from -0.9V to -5.0V , it can use to the negative power supply of CMOS image sensor.
