12 VOLT TO 9 VOLT
REDUCER
QI have a question that I’ve
been trying to figure out for
the past six months. Any
advice you might have will be
greatly appreciated.
I live in the woods and use
12V batteries for power. I have a
bunch of music equipment like
pedals and samplers that run off
of nine volts (mostly 500 mA) and
I would like to make a converter 12V
to 9V DC. Do you think it would
be fine to just use a resistor? Do
you have a simple schematic to
recommend?
I found one that uses an ECG184,
but I am not sure if it will put out the
1.5 amps that I would require to use
three pedals at once.
