TS7809B Datasheet | Taiwan Semiconductor

Description These voltage regulators are monolithic integrated circuits designed as fixed-voltage regulators for a wide variety of applications including local, on-card regulation. These regulators employ internal current limiting, thermal shutdown, and safe-area pensation. With adequate heatsink they can deliver output currents up to 1.5 ampere. .. Although designed primarily as a fixed voltage regulator, these devices can be used with external ponents to obtain adjustable voltages and currents. This series is offered in 3-pin TO-220, ITO-220 package. Features Output current up to 1.5A No external ponents required Internal thermal overload protection Internal short-circuit current limiting Output transistor safe-area pensation Output voltage offered in 4% tolerance Standard Application Ordering Information Part No. TS78xx BCZ TS78xx BCI Operating Temp. 0 ~ +125 C o Package TO-220 ITO-220 Note: Where xx denotes voltage option. A mon 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.
