LV5680

Overview The LV5680P is a multiple voltage regulator for car audio system. This IC has 4 voltage regulators and 2 high-side switches. The following protection circuits are integrated: over current limiter, overvoltage protection and Thermal Shut Down. This IC is most suitable Car Audio.

Features 4 LDO regulators

・ For VDD: Vout is 5.0V, Iomax is 200mA

・ For CD: Vout is 8.0V, Iomax is 1300mA

・ For Illumination: Vout is 8V to 12V(Adjustable external resistors), Iomax is 300mA

・ For Audio: Vout is 8V to 9V(Adjustable external resistors), Iomax is 300mA

2 High-side Switches EXT

：Voltage difference between input and output is 0.5V, Iomax is 350mA ANT

：Voltage difference between input and output is 0.5V, Iomax is 300mA 2 Switches connected to “VDD” SW5V
