Performance/Functional Specifications

All models are tested and specified with external 22μF tantalum input and 10 || 1μF output

capacitors.These capacitors are necessary to accommodate our test equipment and may not

be required to achieve specified performance in your applications. 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 appli-

cation 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.
