TYPICAL APPLICATION
CIRCUIT DESCRIPTION
The TDA8136isa 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 voltageof this
lastis connectedat Pin1(VIN1), the regulator2 will
not workif the Pin1is not supplied.is possibleto switch-offthe output voltage2 (VO2) appling at Pin3 (disable input)a low TTL
level.
