Applications Information
Design Considerations
The TS79Mxx 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 current 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 regula-
tor 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 mF 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 regulator’s 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.
