LV5680P
Multi Voltage Regulator IC
Application Note
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：Voltage difference between “VDD” and output is 0.2V, Iomax is 200mA
ACC(Accessory Voltage Detector output)：Voltage difference between “VDD” and output is 0.2V,
Iomax is 100mA
Over Current Limiting
Overvoltage Protection (Without VDD-OUT) *Detection voltage is 21V(typical)
Thermal Shut Down *175℃(typical)
ACC voltage detector
Maximum surge peak Voltage is 50V
Low thermal resistance package “HZIP15J”(θjc=2℃/W)
(Warning) The protector functions only improve the IC’s tolerance and they do not guarantee the safety of the IC if used
under the conditions out of safety range or ratings. Use of the IC such as use under overcurrent protection range or
thermal shutdown state may degrade the IC’s reliability and eventually damage the IC.
