Circuit that would output 5 volts

Circuit that would output 5 volts

Circuit that would output 5 volts

(OP)
I have a pressure sensor that needs 5 volts, and I have 12 to 13 volts available in the car. Is there a circuit I can put together that can deliver 5 volts.

RE: Circuit that would output 5 volts

Use a USB charger? But that might be 4.5V. How much current do you need?

RE: Circuit that would output 5 volts

(OP)
like .1 amps .... it needs to be very close to 5.0 volts, any variation and it throws the reading off

RE: Circuit that would output 5 volts

Found this on Amazon.

Thanks

RE: Circuit that would output 5 volts

If this device is not specifically for automotive use you may consider some type of input protection across the input. Possibly a Zener diode. You can get some nasty load dump surges from an automotive alternator.

7805 data sheet will have a circuit you can build easily. LM7805
