For VKA = VREF,
Stable for CL = 1 pF to 10k nF
The areas under the curves represent conditions that may cause the device to oscillate. For VKA = 2-V and 3-V curves, R2 and Vbat were adjusted
to establish the initial VKA and IK conditions with CL = 0. Vbat and CL then were adjusted to determine the ranges of stability.

Operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied.
