hi -
i am learning about electronics and want to be extra cautious about power supplies, so i am posting here to make sure i understand this concept correctly.
i currently use a +/-15v power supply that delivers 3a of power.
i'd like to use a variable voltage regulators to provide +/- 5v to certain circuits.
it seems that the most readily available variable regulators are the LM337 and the LM317 - positive and negative voltage regulators, rated at 1.5a.
can i use these regulators, if the lower-voltage circuit itself doesn't draw more than 1.5 amps of power? or is the amperage rating more specifically rated to what is coming from the power supply, initially?
the issue is that i seem to be able to find a 3a voltage regulator for positive voltages (the LM350) - but i see in certain places that it is discontinued. also, i can't seem to find a negative voltage counterpart.
