Voltage Drop Alternatives for Analog Power Circuit.

I would like to design Power supply with very stable and low ripple for analog measurement application.

For regulation from +15 to +5V, from -15 to -5V 3A, about 3Vx3A voltage drop is needed for too much heat.

Please advice me a better alternative for voltage drop under stabilty and ripple basis.
Which one would be better among (1)- wirewound resistor and (2) diodes alternative as attached?
Or does any other better alternatives exist?

Awaiting kind response,
Thanks.

Agreed. For the price of the wirewounds that are high enough wattage to handle the conversion, and the linear regulator, you could put a nice cool switcher together.

You'll get ripple with a switcher, but you can add on low-pass filter stages to the output in order to reduce/eliminate the ripple.
