Voltage Regulators with Higher Voltage than Stock

[Grant Lenahan]

you can also get a variable voltage regulator in a T0-220 case and set it to your own desired voltage. You use a voltage splitter ( tw resistors) anda diode. The complete circuit is generally on the package or in the manufacturers' data book, which assume today is ont he web.

Be careful over-voltaging things. It can cause premature degradation over time.

Or sudden of course,

I've seen discussion of this over the years, that the stock regulator will regulate the voltage down to approx 13.5 whereas there are some plug-in compatible replacements that will regulate closer to 14.5.
