Monolithic Linear IC
For Car Audio Systems
Multi Voltage Regulator IC
Overview
The LV5683P is a multi voltage regulator suitable for USB silicon tuner car-audio systems. This IC has 4 outputs, VDD
5V(3.3V), AUDIO(8.5V), SWU(3.3V) and USB5V(CD 8V: available). About protection circuits, it has
Over-current-protection, Over-voltage-protection and Thermal-shut-down. VCC1(SWU and USB supply) is independent
terminal from VCC, and accepts lower voltage(ex. From DC/DC converter) which enables to reduce power dissipation.
Features
• 4 system regulator
VDD(LCD micon) : VOUT 5.0V(3.3V), IO max 300mA, reverse current prevention.
Audio
: VOUT 8.5V, IO max 300mA
SWU(systems) : VOUT 3.3V, IO max 500mA
USB
: VOUT 5.0V(8.0V available for CD), IO max 1100mA
• Over-current-protection
• Over-voltage-protection: Typ 21V(except VDD)
• Thermal-shut-down Typ 175ºC
• Applied Pch-LDMOS for output stages.
(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 shut down state may degrade the IC’s reliability and eventually
damage the IC.
