APPLICATIONS
V
The V
higher than any of the three main power source voltages
to allow the control of N-channel MOSFET switches. This
micropower, step-up voltage regulator is powered by the
highest potential available from the three main power
sources for maximum regulator efficiency.

Three external components are required by the V
lator: L1, C1 and C2, as shown in Figure 5.
L1 is a small, low current, 1mH surface mount inductor. C1
provides filtering at the top of the 1mH switched inductor
and should be at least 1 F to filter switching transients.
