LA5685N

Ordering number:ENN4185 Monolithic Linear IC LA5685N Multifunction, Multi-Power Supply IC for Car Radios Overview The LA5685N is a multifunction, multipower supply IC developed for car radios. It has 8.5V AM output, 8.5V FM output, 8.5V common output, 5.2V microcomputer output, and 5.1V bias output, making it the ideal power supply for LA1833 and LA1887 ICs for FM/AM tuner systems. Features A total of five built-in outputs : V1=8.5V (AM), V2=8.5V (FM), V3=8.5V (common), V4=5.2V (microcomputer), and V5=5.1V. R ON/OFF, FM/AM switching functions. Minimal static current for backup (120µA typ). Built-in overvoltage protection circuit (V1, V2, and V3 go off at 28V (typ.), V4 and V5 go off at 56V (typ)). Built-in thermal shutdouwn circuit (output goes off at Tj=170°C (typ.)). Built-in short protection circuit.
