TS7900 Series 3-Terminal Fixed Negative Voltage Regulator TO-220 ITO-220 Pin Definition: 1. Ground 2. Input (tab) 3. Output General Description The TS7900 series of fixed output negative voltage regulators are intended as complements to the popular TS7800 series device. These negative regulators are available in the same seven-voltage options as the TS7900 devices. In addition, one extra voltage option commonly employed in MECL systems is also available in the negative TS7900A 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 heat sinking they can deliver output currents in excess of 1 ampere. This series is offered in 3-pin TO-220, ITO-220 & TO-263 package. Features ● ● ● ● ● ● ● Output Voltage: -5 & -12V Output current up to 1A No external components required Internal thermal overload protection Internal short-circuit current limiting Output transistor safe-area compensation Output voltage offered in 4% tolerance Standard Application Circuit Ordering Information Part No. TS79xxCZ C0 TS79xxCZ C0G TS79xxCI C0 Package TO-220 TO-220 ITO-220 Packing 50pcs / Tube 50pcs / Tube 50pcs / Tube TS79xxCI C0G ITO-220 50pcs / Tube Note: W here xx denote voltage option “G” denote for Green Product Halogen Free A common ground is required between the input and the output voltages. The input voltage must remain typically 2.0V above the output voltage even during the low point on the Input ripple voltage. XX = these two digits of the type number indicate voltage. * = Cin is required if regulator is located an appreciable distance from power supply filter. ** = Co is not needed for stability; however, it does improve transient response.
