Optional Diode Protection Circuit
Optional Protection 1:
Add a blocking diode to Vout if
current can flow backwards into
the output, as this can damage
the converter when it is powered
down.
The diode can either be fitted
across the device if the source is
low impedance or fitted in series
with the output (recommended).
