General Description
              The LM78XX 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  poin t 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  LM78XX  series  is  available  in  an  aluminum  TO-3  package which will allow over 1.0A load current 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. Considerable effort  was expanded to make the LM78XX series of regulators easy to use and mininize the number of external components. It is not  necessary  to bypass the output, although this does improve transient response. Input bypassing is needed only if the regulator is located far from the  filter  capacitor of  the  power  supply. For  output  voltage  other than 5V, 12V  and  15V the LM117  series  provides  an  output  voltage  range  from 1.2V to 57V.
