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.

Design considerations
The L78M 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 shortcircuit 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 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.
