LV56831P
Monolithic Linear IC
For Car Audio Systems
Multi Voltage Regulator IC
Overview
The LV56831P has 4 system regulator, VDD 5V(3.3V), AUDIO(8.5V), AMP remote(12V) and REG(3.3V/5V select).
About protection circuits, it has Over-current-protection, Over-voltage-protection and Thermal-shut-down. AMP remote
and REG supply is independent terminal from VCC.,
Features
• 4 system regulator
VDD(LCD micon) : VOUT 5.0V(3.3V), IO max 300mA, reverse current prevention.
Audio
: VOUT 8.5V, IO max 400mA
AMP remote
: VOUT 12V, IO max 500mA
REG3.3/5V
: VOUT 3.3V(5V), IO max 500mA
• 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.
