CIRCUIT DESCRIPTION The TDA8136 is a dual voltage regulator with disable. 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 TYPICAL APPLICATION

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 (VO2) by appling at Pin 3 (disable input) a low TTL level.
