Performance
The following series of scope plots shows the performance
of the LP2995 evaluation board when it is subjected to
various load tests. On each of the six scope plots there are
two traces. The upper trace is the V
has been AC coupled with a scale of 20mV per division. The
The LP2995 has been designed to accommodate several
different capacitor options to allow the designer to optimize
the solution for the specific application. For most desktop
systems large aluminum electrolytic capacitors will be used
for their low cost. However, in height limited situations such
