LV56831P

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.
