L78MxxAB L78MxxAC Precision 500 mA regulators Datasheet - production data Features Output current to 0.5 A Output voltages of 5; 6; 8; 9; 10; 12; 15; 24 V Thermal overload protection Short circuit protection Output transition SOA protection 2 % output voltage tolerance Guaranteed in extended temperature range TO-220 DPAK Description The L78MxxA 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 shutdown and safe area protection, making it essentially indestructible. If adequate heat sinking is provided, they can deliver over 0.5 A output current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltage and currents. Table 1.

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 0.33 F 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 17.

Short-circuit protection Note: 18/31 The circuit of Figure 19 can be modified to provide supply protection against short-circuits 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.
