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 100mA LDO with conection error detection for antenna.
The IC supplies the power for external connection equipment of car navigation (GPS, TV, Microphone), and detect open or short-circuit of output load.
To shut down LDO output automatically when short detection, it also improve safety.
