L200 VOLTAGE REGULATOR SOFT START MECHANISM ELECTRONIC DIAGRAM
L200 VOLTAGE REGULATOR SOFT START MECHANISM ELECTRONIC DIAGRAM
The Vo follows the voltage at pin 2 at less than 0.45 V since a voltage of more than 0.45 V cannot be produced between pins 5 and pins 2.
Constant current ic is charge capacitor C, where
ic= Vsc/R
After the time ton, the output reaches it’s nominal value
Vo-Vsc = (Ic.ton)/C
ton=C.[(Vo-0.45)/0.45].R = CVoR/0.45
