L78xxAB L78xxAC Precision 1 A regulators Features ■ ■ ■ ■ ■ ■ Output current in excess of 1 A Output voltages of 5; 6; 8; 9; 12; 15; 24 V Thermal overload protection Output transition SOA protection 2 % Output voltage tolerance Guaranteed in extended temperature range TO-220 TO-220FP Description The L78xxAB L78xxAC series of three terminal positive regulators are available in TO-220, TO-220FP, and D2PAK 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 1 A output current, although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltage and currents.

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 0.33 µF 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 2 V 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. Figure 8.
