This versatile power supply module provides two 15V outputs or one +/-15V output depending on the wiring, as well as a 5V output. The voltage of each output is adjustable, from 5V to 20V for the former and from 3.3V to 5V for the latter. The module achieves low noise and ripple thanks to the use of LDO LT1764 regulators. The input is done on two 12V inputs and/or on one 9V input. The module also integrates a short-circuit protection at the output and a thermal protection.
