Is there a Voltage regulator with high/low (on/off) pin?

Is there a Voltage regulator with high/low (on/off) pin?

Is there a Voltage regulator with high/low (on/off) pin?

(OP)
I'm whipping up a circuit that uses +15V via a standard Voltage regulator. I'd like to have the regulator shut off, or turn off, when a transient voltage is applied.
i.e. a separate DC voltage is introduced into my circuit and i want to use that to shut off the regulator.

Can a diode do this?

Thx,

thanks, sure a diode can do that would rather find a neat voltage regulator that does it similar to a diode. Or what i meant was can anyone suggest a good diode circuit that can do it.

Thanks for your help

There are heaps of vregs out there with enable input.

Benta.
