Performance/Functional Specications
Typical @ TA = +25°C under nominal line voltage, VOUT=5V, and full-load conditions unless noted.
All models are tested and specied 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 specied 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
ltering. See I/O Filtering and Noise Reduction.
MTBF’s are calculated using Telcordia SR-332(Bellcore), ground xed, TA = +25°C, full
power, natural convection.
Do not exceed maximum rated output power when adjusting the output voltage.
Input Voltage:
Continuous or transient
14 Volts
On/Off Control (Pin 11)
+VIN
Input Reverse-Polarity Protection
None
Output Overvoltage Protection
None
Output Current
Current limited. Devices can
withstand sustained output short
circuits without damage.
Storage Temperature
–40 to +125°C
Lead Temperature (soldering, 10 sec.)
+280°C
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 Specications Table is not implied.
