Can I get a 150V DC output from the circuit below by using LM317HV-MIL? As the voltage input I will be using a 160V unregulated input voltage from a rectifier.
If so, is there anything that I have to be careful such as power ratings, Vmax, Vce, etc. of the resistors, transistors, capacitors, etc.?
Here is the datasheet: http://www.ti.com/lit/ds/symlink/lm317hv-mil.pdf
Thanks for your help in advance.
EDIT1:
Datasheet says, " Since the regulator is floating and sees only the input-to-output differential voltage, supplies of several hundred volts can be regulated as long as the maximum input to output differential is not exceeded, or in other words, do not short the output to ground."
What I did not get is if the input is 160V, I will need C1 have a voltage rating higher than 160V as well as C2 and C3. Is that right? Also, what should be the power ratings of the resistors R5 and R4. Could you help me to calculate the required power rating? For 150V, I calculate it as around 5W. What the R4?
EDIT2:
How about this?

It is possible but not this way. the 0V reference level for ADJ bias current must be level shifted up to say 140V using an "active zener" voltage divider regulator.

Use 140V active Zener + 10V LM317 design = 150V
