Default Stab Design Program

Thanks for sharing this small handy program, i like it !

Any technical information on lm317 shuntregulator regarding: PSSR, regulation, output resistance versus frequency?

thx for program and el cap schematic

have you measured or simulated noise and pssr of your LM317 based regulator
can we use higher values for caps at adj and output of LM317 - say 100 - 220 uF

Default Sounds good but transistors are hot

Hi Nazar,
i've built the regulator presented by you used in your DAC-s and it sounds really good but my transistors (especially last one) are running very hot.
I'm using it to power only one opamp wich is a LPF for a DAC.
What should error should i check ?

Thanks a lot,
Adrian
