1 three-terminal positive-voltage regulator niko-sem L78L00 series may-31-2001 general description this series of fixed-voltage monolithic integrated circuit voltage regulators is designed for a wide range of applications. these applications include on-card regulation for elimination of noise and distribution problems associated with single- point regulation. in addition, they can be used with power-pass elements to make high-current voltage regulators. one of these regulators can deliver up to 100 ma of output current. the inter- nal limiting and thermal shutdown features of these regulators male them essentially immune to overload. when used as a replacement for a zener diode-resistor combination, an effective improvement in output impedance can be obtain -ed together with lower-bias current. features z 3-terminal regulators z output current up to 100 ma z no external component z internal thermal overload protection z internal short-circuit current limiting z direct replacements for lm78l00, a78l00 and an78l00 series applications z linear regulator z instrumentation z switching power supplies z pcs, industrial equipment pin configurations device selection guide device l78l05n l78l05c l78l12n l78l12c package to-92 sot-89 to-92 sot-89 marking 78l05 78l05 78l12 78l12 free datasheet http://www..net/
