The TDA8132 is a dual voltage regulator with sepa-

rate 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

not supplied.

The outputs stage have been realized in darlington

configuration with a drop typical 1.2V.

For each output a disable circuit switches-off this

output if a voltage lower than 0.8V is applied at

corresponding Pin (Pin 3 for output 2, Pin 5 for

output 1).
