fixed voltage regulator lm78lxx 3-terminal 0.1a positive voltage regulators 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. each of these regulators can deliver up to 100? of output current. the internal limiting and thermal shutdown features of these regulators make them essentially immune to overload. when used as a replacement for a zener diode-resistor com- bination, an effective improvement in output impedance can be obtained together with lower-bias current. ordering information device marking package lm78lxx lm78lxx to-92 features lm78l05 /a /c lm78l05 /a /c output current up to 100? lm78l05nf 805 sot-89 no external components lm78l05af/cf internal thermal overload protection lm78l06f~24f 806~824 internal short-circuit limiting xx = output voltage or grade output voltage of 5v, 6v, 8v, 9v, 10v, 12v, 15v, 18v and 24v absolute maximum ratings characteristic symbol value unit input voltage lm78l05 /a/c lm78l10 v i 30 v LM78L12 lm78l18 35 lm78l24 40 operating junction temperature topr 0 +150 storage temperature tstg -65 +150 soldering temperature and time tsol 260/10sec mar. 2006 - rev 06 htc 26 to-92 (top view) 1. output 2. gnd 3. input 1. 1. sot-89
