Stability Boundary Conditions
TL431
Note: The areas under the curves represent conditions that may cause the
device to oscillate. For curves B, C, and D, R2 and V+ were adjusted to
establish the initial VZ and IZ conditions with CL = 0. V+ and CL were then
adjusted to determine the ranges of stability.
