TheTDA8132is a dualvoltageregulatorwithseparate Disablefor each output.
The two regulation parts are supplied from one
voltage reference circuit trimmed by zener zap
during EWS test.

The outputsstagehave beenrealized in darlington
configurationwith 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).
