APPLICATION INFORMATION
estimating maximum load capacitance
For worst-case constant-current load of value just less than the trip limit, C
OUT(max)
can be estimated from:

Where V
OUT
is the output voltage and I
MAX
is the maximum sourcing current.
For a resistive load of value R
LOAD
, the value of C
OUT(max)
can be estimated from:
