MC79xxCT Series Vishay New Product formerly General Semiconductor 3-Terminal Fixed Negative Voltage Regulators Pin Arrangement Description These voltage regulators are intended as complements to the popular MC78xx Series devices. These negative regulators are available in the same seven-voltage options as the MC78xx devices. In addition, one extra voltage option commonly employed in MECL systems is also available in the negative MC79xx Series. TO-220 1. Ground 3 2. Input 2 1 3. Output (heatsink connected to pin 2) Available in fixed output voltage options from –5.0 to –24 volts, these regulators employ current limiting, thermal shutdown, and safe-area compensation – making them remarkably rugged under most operating conditions. With adequate heatsinking they can deliver output currents in excess of 1.5 ampere. Standard Application Features Input Output MC79xx • Output current in excess of 1.5 Ampere • No external components required Co 0.1µF Cin 0.33µF • Internal thermal overload protection • Internal short-circuit current limiting • Output transistor safe-area compensation • Output voltage offered in 2% tolerance Notes: A common ground is required between the input and the output voltages. The input voltage must remain typically 2.0V more negative even during the high point on the input ripple voltage. Mechanical Data Case: TO-220 Package Weight: approx. 2.24g xx = these two digits of the part number indicate output voltage. Cin is required if regulator is located an appreciable distance from power supply filter. Case outline is on the back page Co improves stability and transient response.
