TS7900A series 3-Terminal Fixed Negative Output Voltage Regulator TO-263 Pin assignment: 1. Ground 2. Input 3. Output (Heatsink surface connected to Pin 2) Voltage Range - 5V to - 24V Output Current up to 1.5A General Description The TS7900A series of fixed output negative voltage regulators are intended as complements to the popular TS7800A series device. These negative regulators are available in the same seven-voltage options as the TS7800A devices. 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 sink they can deliver output currents in excess of 1.5 ampere. This series is offered in 3-pin TO-220, TO-263 package. Features Standard Application Output current up to 1.5A No external components required Internal thermal overload protection Internal short-circuit current limiting Output transistor safe-area compensation Output voltage offered in +/-2% tolerance Ordering Information Part No. TS79xxACZ Operating Temp. (Ambient) o -20 ~ +85 C Package TO-220 TO-263 TS79xxACM 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.
