Data Sheet
5.3
The Buck converter is due to the parasitic source drain diode of the DMOS not reverse
polarity protected. Therefore, as an example, the reverse polarity diode is shown in the
application circuit, in general the reverse polarity protection can be done in different
ways.
5.4
As indicated before the linear regulators show stable operation with a minimum of 470nF
ceramic capacitors. To avoid a high ripple at the output due to load steps this output cap
might have to be increased to some few µF capacitors.
5.5
The voltage trackers require at their outputs 1µF ceramic capacitors each to avoid some
oscillation at the output. If needed the tracker outputs can be connected in parallel, in that
the output capacitor increases linear according to the number of parallel outputs.
5.6
The undervoltage/watchdog reset outputs are open drain structures and require external
pull up resistors in the range of 10k to the µC I/O voltage rail.
