➀ 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.
➁ See Technical Notes for details.
➂ 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.
➃ Output noise may be further reduced with the installation of additional external output
capacitors. See Technical Notes.
➄ These signals must be referenced to the input return pin (–VIN).
➅ Demonstrated MTBF available on request.
