Sorry if this has already been asked, couldn’t find anything similar.
It looks like virtually all usb style power supplies are giving 5.4 - 5.5v vin. Unfortunately my new product design must use 3 x pressure sensors that require 4.8 - 5.2 v vcc. I’ve already fried one today with 5.5v
Any suggestions as to which voltage regulator to use? The 5.x vin is also being used to provide dirving power for 4 x relays so needs to provide minimum 500ma current (the sensors only draw typ 7ma and max 10ma each, 4 x relay drive is about 100 ma so 500ma is probably overkill, but would prefer to be safe.
Signal return from sensor is max 4.8v, using divider to insure max 3.3v for analog input.
Note 3.3v sensors cost $70 - $80 compared to $7-$8 for 5…0v sensors, and as this is a commercial product in development, price means we have to use the 5.0v vcc sensors.
Thanks in advance
