~ All models are tested/specified with external 22μF input/output capacitors.These caps accommo-
date our test equipment and may not be required to achieve specified performance in your applica-
tions. All models are stable and regulate within spec under no-load conditions.
 See Technical Notes and Performance Curves for details.
€ The On/Off Control (pin 11) is designed to be driven with open-collector logic or the application of
appropriate voltages (referenced to Common, pins 5 and 6).
 Output noise may be further reduced with the installation of additional external output filtering. See
I/O Filtering and Noise Reduction.
