Length: 0.17” (4.32mm) Weight 0.3 ounces (8.5g) Flamability Rating UL94V-0 Performance/Functional Specifications Typical @ TA = +25°C under nominal line voltage, VOUT=5V, and full-load conditions unless noted. 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. MTBF’s are calculated using Telcordia SR-332(Bellcore), ground fixed, 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 Specifications Table is not implied. Absolute Maximum Ratings |
