I guess I misread your other post about the transistor amplifier configuration. If a small resistor was added to the emitter and ground, and was bypassed with a high capacity, high current poly type of capacitor, the transistor would have some built in thermal stability due to this negative feedback.

Yes, I am suggesting a load resistor be added to the regulator, pi filter junction to help with switching/keying time constants. I'm assuming the pi filter is to keep RF out of your supply, so make the resistor value equal to the filters insertion impedance for proper loading.
