Models are specified at "full load" (5V & 3.3V @ 7.5A), with an external 22µF, low-ESR,
input capacitor and 10µF tantalum in parallel with 1µF ceramic output capacitors.
See Technical Notes for details.
Devices may be ordered with opposite polarity (pin 3 open = off), or the On/Off Control
function can be replaced with a sync function. See Part Number Suffixes and Technical
Notes for additional information.
Output noise may be further reduced with the installation of additional external output
capacitors. See Technical Notes.
These signals must be referenced to the input return pin (–VIN).
