Figure 15 – Stability Boundary Conditions
*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 VKA and IK conditions with CL = 0. VBATT and CL were then adjusted to
determine the ranges of stability.
