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. 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.

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. 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. Co improves stabi……
