L5950 Voltage regulator with I²C bus, very low stand-by current and low spread output voltage

The ASPM (Audio System Power Module) is an integration of three high side drivers and five regulators developed to provide the power for an audio system.

The outputs of the IC are controlled via the I²C bus and the Enable input.

External protection must be provided for reverse battery protection.
