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.

L78MxxAB, L78MxxAC Applications information

7 Applications information

7.1 Design considerations

The L78MxxA 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 0.33 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 20. Short-circuit protection

Note: The circuit of Figure 19 can be modified to provide supply protection against short-circuits

by adding a short-circuit sense resistor, R

, and an additional PNP transistor. The current

SC

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.
