I use a dspic33 series pic and a sensor which need 5v supply. The problem is that the microcontroller use 3.3V supply. From what i know , sensor and microcontroller need to be connected with the same power supply .

Never do that, it is a bad way to power any IC, as internal resistances and other varying load resistances will reduce your voltage further down, eventually your IC will reset or simply does not work.
for input voltage u shoul be taking
1> adapter of 12v
2> 9 -o-9 ct transformer with power supply ckt of 7812 ic(78 means + and 12 means 12 volt) (+12 v)
if u r using <1> ,<2> then u simply connect your LM337 to the adpater output>>>> for getting 5v give the value of resistor in the link i am providing now
hope u eind it helpful
god bless
U can get any desired voltage by just changing the value of resistors in lm 317..i had been using this and is really of greaty help try this https://www.pcsilencioso.com/cpemma/317calc.html
