TDA8136 Datasheet, PDF (4/5 Pages) STMicroelectronics – DUAL 12V REGULATOR WITH DISABLE

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 (VIN1), the regulator 2 will
not work if the Pin 1 is not supplied.
It is possible to switch-off the output voltage 2 (V_O2)
by appling at Pin 3 (disable input) a low TTL
level.
