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 secondary 250mA LDO with conection error detection.
The IC supplies the power for external connection equipment of car navigation (GPS/TV/Radio/Microphone/Camera), and detect open/short-circuit of output. Open/Short detection function can be used in stand-alone without ADC and high accuracy detection by individual setting.
It can be easily to configure power supply circuit by the power supply fault protection and short-flag delay function for the rush current.
