LM78LXX April 2006 LM78LXX Series Series 3-Terminal Positive RegulatorsGeneral Description nal power dissipation. If internal power dissipation becomestoo high for the heat sinking provided, the thermal shutdown 3-T The LM78LXX series of three terminal positive regulators is circuit takes over preventing the IC from overheating. available with several fixed output voltages making them erminal useful in a wide range of applications. When used as a zener Features diode/resistor combination replacement, the LM78LXX usu-ally results in an effective output impedance improvement of n LM78L05 in micro SMD package two orders of magnitude, and lower quiescent current.
