ence, digitally trimmed, assures the selected out-
put voltage to within +/-1% over temperature and
battery voltage variations.
Thanks to the remote sensing inputs and to the
window comparator system, embedded in the er-
ror summing structure, the device provides excel-
lent load transient performance. The high peak
current gate drive affords to have fast switching
to the external power mos, performing an high ef-
ficiency. A complete power management include
on board a programmable power-up sequencing,
power good signal, skip mode operation and un-
dervoltege detection. The L5996 assures a fast
protection against load overvoltage and load
overcurrent. Linear regulator on-board is avail-
able with an output voltage of 2.5V (+/-2%) and a
current capability of
150mA, useful for CPU
CLOCK BUS.
