CIRCUIT DESCRIPTION The TDA8132 is a dual voltage regulator with separate Disable for each output. The two regulation parts are supplied from one voltage reference circuit trimmed by zener zap during EWS test. Since the supply voltage of this last is connected at Pin 1 (VIN1), the regulator 2 will not work if Pin 1 is ABSOLUTE MAXIMUM RATINGS
