lm7805ct - lm7812ct- LM7824CT 02/10/2012 comset semiconductors 1/3 positive voltage regulators general description this series of fixed-voltage 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. each of these regulators can deliver up to 1.5a of output current. the internal current-limiting and thermal-shutdown features of these regulators essentially make them immune to overload. in addition to use as fixed-voltage regulators, these devices can be used whit external components to obtain adjustable output voltages and currents, and also can be used as the power-pass element in precision regulators. compliance to rohs. features ? 3-terminal regulators ? output current up to 1.5a ? internal thermal-overload protection ? output transistor safe-area compensation ? with to220 package absolute maximum ratings symbol ratings value unit v i input voltage dc v o = 5 v to 18v 35 v v o = 20 v & 24v 40 i o output current internally limited p d power dissipation internally limited t op operating junction temperature 0 to 150 c t stg storage temperature -55 to 150 c thermal data symbol ratings value unit r thjc from junction to case thermal resistance 5 c/w r thja from junction to free-air thermal resistance 50 www.datasheet.net/ datasheet pdf - http://www..co.kr/
