DESCRIPTION
The TDA8136 is a monolithic dual positive voltage
regulator designedto provide fixed precision output
voltages, both 12V at currents up to 600mA.
Output 2 can be disabled by a TTL input. Both
output currents are limited by an internal short
circuit protection.

TDA8136
CIRCUIT DESCRIPTION
The TDA8136 is a dual voltage regulator with dis-
able.
The two regulation parts are supplied from one
vol-tage reference circuit, trimmed by zener zap
during EWS test. Since the supply voltage of this

last is connected at Pin 1 (V

), the regulator 2 will
not work if the Pin 1 is not supplied.
It is possible to switch-off the output voltage 2 (V

)
by appling at Pin 3 (disable input) a low TTL
level.
