LM78LXX Series 3-Terminal Positive Regulators
General Description
The LM78LXX series of three terminal positive regulators is
available with several fixed output voltages making them
useful in a wide range of applications When used as a ze-
ner diode resistor combination replacement the LM78LXX
usually results in an effective output impedance improve-
ment of two orders of magnitude and lower quiescent cur-
rent These regulators can provide local on card regulation
eliminating the distribution problems associated with single
point regulation The voltages available allow the LM78LXX
to be used in logic systems instrumentation HiFi and other
solid state electronic equipment
The LM78LXX is available in the metal three-lead TO-39(H)
package the plastic TO-92 (Z) package and the plastic
SO-8 (M) package With adequate heat sinking the regulator
can deliver 100 mA output current Current limiting is includ-
ed to limit the peak output current to a safe value Safe area
protection for the output transistors is provided to limit inter-
nal 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
