description the sp7800 series of th ree-terminal positive regulators is available in to-220 packages and several fixed output voltages, making it useful in a wide range of applications . these regulators can provide local on-card regulation, eliminating the distribution problems asso ciated with single point regulation. each type employs internal current limiting, thermal shut-down and safe area protection, making it essent ially indestructible. if adequate heat sinking is provided, they can deliver over 1a output current. although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltage and currents. features ? output current to 1.5a ? output voltages of 5; 8;12v ? thermal overload protection ? short circuit protection ? output transiti on soa protection schematic diagram absolute maximum ratings symbol parameter2 value unit v i dc input voltage 40 v i o output current internally limited p tot power dissipation internally limited t stg storage temperature range -65 to 150 c t op operating junction temperature range 0 to 150 c 1 of 9 4008-318-123 sales@twtysemi.com http://www.twtysemi.com product specification SP7812
