LM338 voltage regulator 220 package

a linear regulator, or voltage regulator, is a method for supplying a constant voltage. the internal resistance of the regulator varies according to the load resistance, resulting in a stable output voltage. the lm338 voltage regulator is one of the adjustable voltage regulators in the range of 1.2 to 37 volts with a maximum output current of 7 amperes. this voltage regulator is designed and produced in a to-220 package. the voltage regulation element is designed to operate like a variable resistor and continuously adjusts a voltage divider circuit to provide a stable output voltage, while always dissipating the voltage difference between the input and output of the circuit as heat
