D24V22F5 - Reducing output voltage


#1

Hi I want to use the D24V22F5 regulator to power a M590 GSM module, however the maximum supply voltage is 4.7 Volts. Could you tell me what feedback resistors I would need to change to reduce the output from 5V to 4V?

Thanks

Simon

Hi, Simon.

To get a 4V output from your D24V22F5 regulator you should change the resistor (R4) shown in the picture below to a 6.2k 0603 resistor.

Hi Clare,

Thanks for the quick response, I’ll give that a go.

Kind regards

Simon
