LM78L00 Series
3-Terminal Positive Voltage Regulators
General Description
The LM78L00 series of 3-terminal positive voltage regula-
tors employ internal current-limiting and thermal shutdown
making them essentially indestructible If adequate heat
sinking is provided they can deliver up to 100 mA output
current They are intended as fixed voltage regulators in a
wide range of applications including local (on-card) regula-
tion for elimination of noise and distribution problems asso-
ciated with single-point regulation In addition they can be
used with power pass elements to make high current volt-
age regulators The LM78L00 used as a Zener diode resis-
tor combination replacement offers an effective output im-
pedance improvement of typically two orders of magnitude
along with lower quiescent current and lower noise
