august 2006 rev. 4 1/26 26 l78m00ab/ac series precision 500ma regulators feature summary output current to 0.5a output voltages of 5; 6; 8; 9; 10; 12; 15; 18; 24v thermal overload protection short circuit protection output transition soa protection 2% output voltage tolerance guaranteed in extended temperature range description the l78m00ab series of three-terminal positive regulators is available in to-220 and dpak packages and with 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 associated with single point regulation. each type employs internal current limiting, thermal shut- down and safe area protection, making it essentially indestructible. if adequate heat sinking is provided, they can deliver over 0.5a output current. although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltage and currents. dpak to-220 www.st.com schematic diagram

applications information l78m00ab/ac series 18/26 6 applications information 6.1 design considerations the l78m00ab series of fixed voltage regulators are designed with thermal overload protection that shuts down the circuit when subjected to an excessive power overload condition, internal short-circuit protection that limits the maximum current the circuit will pass, and output transistor safe-area compensation that reduces the output short-circuit as the voltage across the pass transistor is increased. in many low current applications, compensation capacitors are not required. however, it is recommended that the regulator input be bypassed with a capacitor if the regulator is connected to the power supply filter with long wire lengths, or if the output load capacitance is large. an input bypass capacitor should be selected to provide good high-frequency characteristics to insure stable operation under all load conditions. a 0.33f or larger tantalum, mylar, or other capacitor having low internal impedance at high frequencies should be chosen. the bypass capacitor should be mounted with the shortest possible leads directly across the regulators input terminals. normally good construction techniques should be used to minimize ground loops and lead resistance drops since the regulator has no external sense lead. figure 16. current regulator i o = v xx /r 1 +i d figure 17. adjustable output regulator v o = 7.0v to 20v v i - v o 2.0v
l78m00ab/ac series applications information 19/26 note: the circuit of figure 19 can be modified to provide supply protection against short circuits by adding a short-circuit sense resistor, r sc , and an additional pnp transistor. the current sensing pnp must be able to handle the short-circuit current of the three-terminal regulator. therefore, a four-ampere plastic power transistor is specified. figure 18. current boost regulator i o = i reg + q 1 (i reg ______) v beq1 r 1 r 1 = ______________ v beq1 i req -(i q1 / q1 ) figure 19. short-circuit protection
