Linear regulator (LDO)

MM1936

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.

Application

・In-vehicle infotainment device
・Power supply for antenna

Features

Detecting for connected device
