DESCRIPTION
The TDA8132 is a monolithic dual positive voltage
regulator designedto provide fixed precision output
voltages of 5.1V and 12V at currents up to 1A.
Each output can be disabled separately by a TTL
input.
Short circuit and thermal protections are included.

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
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).
