Transistor switch

Using the switch the OP suggested could also destroy
the regulator when it is switched "on".

After destroying the load when it was switched "off".

As a academic problem , the schematic suggested Vin to be ideal voltage
source- and OP kept talking about voltage "across" Rc- which I think he
meant say dropped "by" 0.2V and not "to to" 0.2V- something like this
gets you in the ballpark....

This was my original point, before the possible regulator damage
was pointed out.
However, it depends upon what is supplied by that regulator. I have often
seen regulators used where the components could take higher voltages, but
the stability may be required.
I would expect damage to TTL components, but we don't know what the OP was
going to connect to it and what his input voltage was going to be.
