The areas under the curves represent conditions that may cause the device to oscillate. For curves B, C, and D, R2 and VREF were adjusted to establish the initial VKA and IKA conditions with CL = 0. VBATT and CL then were adjusted to determine the ranges of stability (see Figure 18 and Figure 19 for test circuits).
