二：General Description
TX78XX is three-terminal positive regulators. One of these regulators can deliver up to 500mA of output current. The internal limiting and thermal-shutdown features of the regulator make them essentially immune to overload. When used as a replacement for a zener diode-resistor Combination, an effective improvement in output impedance can be obtained, together with lower quiescent current
