Typical at Ta= +25 C under nominal line voltage and 75% load conditions, unless noted. The information and specifications contained in this brief are believed to be accurate and reliable at the time of publication. Specifications are subject to change without notice. Refer to product specification sheet for performance characteristics and application guidelines. The output voltage can be trimmed (10%) using an external resistor. To trim the output up (down) connect a resistor between pins 5 and 6 (7). A 10K trim pot can also be used to make the output variable. Connect the wiper to pin 5 and make the other connections to pins 6 and 7.
