| TS7900 series 3-Terminal Fixed Negative Output Voltage Regulator ITO-220 Pin assignment: 1. Ground 2. Input 3. Output (Heatsink surface connected to Pin 2) Voltage Range - 5V to - 24V Output Current up to 1A 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 TS7800 devices. In addition, one extra voltage option commonly employed in MECL systems is also available in the negative TS7900 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 ampere. This series is offered in 3-pin TO-220, ITO-220 package. Features 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 Ordering Information Part No. TS79xxCZ TS79xxCI Operating Temp. (Ambient) -20 ~ +85oC Package TO-220 ITO-220 Note: Where xx denotes voltage option. 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.
