LV56831P

www.DataSheet.co.kr Ordering number : ENA1983 Monolithic Linear IC LV56831P Overview For Car Audio Systems Multi Voltage Regulator IC 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) Applied Pch-LDMOS for output stages. Thermal-shut-down Typ 175ºC (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.
