LM7808

LM78XX LM78XX 3-Terminal 1 A Positive Voltage Regulator Pb ® Pb Free Plating Product Features ● ● ● ● ● ● Output Voltage Range 5 to 24V 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 TO-220M-1 Unit : (mm) Standard Application Circuit 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.
