The LM342-XX series of three-terminal regulators is available with several fixed output voltages making them useful in a wide range of applications One of these is local on card regulation eliminating the distribution problems associated with single point regulation The voltages available allow these regulators to be used in logic systems instrumentation HiFi and other solid state electronic equipment Although designed primarily as fixed voltage regulators these devices can be used with external components to obtain adjustable voltages and currents The LM342-XX series is available in the plastic TO-202 package This package allows these regulators to deliver over 0 25A if adequate heat sinking is provided Current limiting is included to limit the peak output current to a safe value Safe area protection for the output transistor is provided to limit internal power dissipation If internal power dissipation becomes too high for the heat sinking provided the thermal shutdown circuit takes over preventing the IC from overheating
