These are stress ratings. Exposure of devices to any of these conditions may adversely
affect long-term reliability. Proper operation under conditions other than those listed in the
Performance/Functional Specifi cations Table is not implied.
These power converters require a minimum 10% output loading to maintain specifi ed
regulation. Operation under no-load conditions will not damage these devices; however
they may not meet all listed specifi cations.

All models are specifi ed with external 33μF, low-ESR, input capacitors and 10μF tantalum
Devices may be ordered with the opposite polarity (pin 3 open = off), or the on/off control
Accuracy is specifi ed with the sense pins tied directly to their respective output pins.
Output noise may be further reduced with the installation of additional external output
