LM79XX ® Pb Free Plating Product LM79XX 3-Terminal 1 A Negative Voltage Regulator Pb 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 TO-220M-1 Unit : (mm) Standard Application Circuit LM79XX 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.
