Hi all,
i need to make a power supply, with 3 DC output
5 V, will need max 0.56A,
7.5V, will need 2A (stepmotors)
12V will need 1A
i guess switching voltage regulators will be better.
i will select all currents a bit higher than max value.
I am confused about different variations :
- Should i first use 12V voltage regulator, and connect output of 12V regulator to 7.5V and 5V DC regulators? or should i use output of 7.5V for input of 5V?
- Should i use multiple output regulator? 12V and 5V output and 7.5V after 12V output? would inductive load effect rest of circuit negative?
What would you suggesst me to do, and why?
Thanks
