TK717xxS
APPLICATION INFORMATION (CONT.)
As shown in the figure below, several components are required to discharge the charge in the output side capacitor in a
typical regulator.
Because the external electrical discharge circuit is unnecessary with the TK717xxS, the application becomes very simple.
Turning the regulator off automatically discharges the charge of the output side capacitor.
The TK112xxB is a normal regulator.
The TK717xx is built with the automatic discharge circuit during off time.
The TK716xxS, AS is built with the output disconnect circuit.
