L7800AB/AC SERIES PRECISION 1A REGULATORS OUTPUT CURRENT IN EXCESS OF 1A OUTPUT VOLTAGES OF 5; 6; 8; 9; 12; 15; 18; 20; 24V THERMAL OVERLOAD PROTECTION OUTPUT TRANSITION SOA PROTECTION 2% OUTPUT VOLTAGE TOLERANCE GUARANTEED IN EXTENDED TEMPERATURE RANGE DESCRIPTION The L7800A series of three terminal positive regulators is available in TO-220, TO-220FP, TO-220FM and D 2 PAK 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 problem 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 1A output current, Although designed primarily as fixed voltage regulators, these TO-220 D 2 PAK TO-220FP TO-220FM devices can be used with external components to obtain adjustable voltage and currents.

APPLICATION INFORMATION DESIGN CONSIDERATION The L7800A 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 current 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 capacitor if the regulator is connected to the power supply filter with long 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 0.33mF 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. The addition of an operational amplifier allows adjustment to higher or intermediate values while retaining regulation characteristics. The minimum voltage obtained with the arrangement is 2V greater than the regulator voltage. The circuit of figure 6 can be modified to provide supply protection against short circuit by adding a short circuit sense resistor, RSC, 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.
