LV4920H Datasheet (Sanyo Semicon Device) - Class-D Audio Power Amplifier

LV4920H, Class-D Audio Power Amplifier

System Standby The built-in 5V regulator is turned on and off under control of the high/low state of the STBYB pin.

When the STBYB pin is low, the regulator will be turned off, and when that pin is high, the regulator will be turned on.

Also, the signal initializes the internal logic of the IC.
