I need idea for the ultra low power consumption High Voltage regulator.
Input 60V (or even 150V).
I want to have linear regulation on the output between 2V and 50V.
I have Input between 0V and 3.3V (maybe 5V) and I need proportional output between 2V and 50V.

if you want to check the power consumption of your circuit from an ideal voltage source (no inductors, or resistors in series with the source), do you use the average or the rms functions? i.e.: average(IT('/V0')) or rms(IT('/V0'))?

In most cases the input power used in PAE formula is neglected compared to output power (due to high gain of the amplifier).
So, never you get high PAE and high power consumption in the same time.

When you apply 15V at the input the zener current is: Iz = (15-Vz)/200 = 52.5mA. The power dissipated by the zener is Pz = Iz Vz = 236mW. It will become hot and your limiting resistor wil too. This is the no load condition. I suspect you are using a small package diode. In this case you are above the shown 200mW spec. A more reasonable no load curr
