L78M Datasheet Precision 500 mA regulators Features TO-220 TO-220FP IPAK DPAK • • • • • • • 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 Output voltage tolerance: 2 % (AB and AC versions) or 4 % (C version) Guaranteed in extended temperature range Description The L78M series of three-terminal positive regulators is available in TO-220, TO-220FP, DPAK and IPAK 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, resulting 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.

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 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. Figure 17. Fixed output regulator AMG080320171807MT Note: Although no output capacitor is need for stability, Co improve transient response if present. CI is required if regulator is located an appreciable distance from power supply filter. Figure 18.
