The areas under the curves represent conditions that may cause the device to oscillate. For V
KA
= 2V and 3V
curves, R2 and V
BAT
were adjusted to establish the initial V

and I
K
conditions with CL = 0. V
BAT
and C
L
then
were adjusted to determine the ranges of stability. As the graph suggested, SE432L is unconditional stable
with I
K
from 0 to 100mA and with C
L
from 0.001uF to 1uF.
