elektronische bauelemente SJ78M05 3-terminal positive voltage regulator 21-oct-2009 rev. b page 1 of 2 rohs compliant product a suffix of ?-c? specifies halogen and lead-free description the SJ78M05 series of three-terminal positive regulato rs are available in the to-252 package and with 5vfixed output voltage, making it useful in a wide range of applic ations. this regulator can provide local on-card regulation, eliminating the distribution problems associated with singl e point regulation.it employs internal current limiting, thermal shut-down and safe operating ar ea protection, making it essentially indestructible. if adequate heat sinking is provided, they can deliver over 0. 5a output current. although designed primar ily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltages and currents. SJ78M05 is characterized for operation from 0 c to +125 c. package dimensions absolute maximum ratings parameter symbol value units input voltage v in 35 v output current i o 500 ma operating temperature range t j , 0~+125 c storage temperature range t stg -65~+150 c total power dissipation p d 1.0* w to-252
