SOFT START MECHANISM FOR L200 VOLTAGE REGULATOR ELECTRONIC DIAGRAM
SOFT START MECHANISM FOR L200 VOLTAGE REGULATOR ELECTRONIC DIAGRAM
Ic (constant current) is charge capacitor C, where Ic = Vsc/R.
The output reaches its nominal value after the time ton. Vo-Vsc=(Ic.ton)/C.
ton=C.[(Vo-0.45)/0.45].R = CVoR/0.45.
Vo follows the voltage in pin 2 at less than 0.45 volt. It is because voltage of more than 0.45 V can’t be produced between pin 2 and pin 5.
