I need to drop 12V to 5V @80mA efficiently (i.e. least amount of energy converted to heat).
Using any kind of switching DC-DC converter is not an option because it will introduce too much noise into the system. (This is for an analog synth)
Should I just use a standard 5V regulator (i.e LM2805 in a TO-92 package?)
Should I drop the voltage down first with some series resistors or diodes?
