IDEAS ON EVALUATING AN LDO
TABLE C-1:
One of the characteristics that a designer may wish to evaluate on a LDO is how the
LDO responds to transient loads. Figure C-2 shows a system block diagram for
evaluating a LDO and a typical waveform response (at test point) for the function
generator signal. The output of the function generator connects to a BJT transistor to
simulate the fast switching loads of the circuit.
The value of C2, R3 and C
Look at both the worst-case amplitude load requirements for a loaded and unloaded
system. As the output response of the LDOs become faster, the selection of a smaller
(cheaper) output load capacitor (C
performance).
