APPLICATIONS INFORMATION
Design Considerations TS79L00 Series fixed voltage regulators designed with Thermal Overload Protection that shuts down circuit when subjected excessive power overload condition, Internal Short-Circuit Protection that limits maximum current circuit will pass. many current applications, compensation capacitors required. However, recommended that regulator input bypassed with capacitor regulator connected power supply filter with long FIGURE POSITIVE NEGATIVE REGULATOR should used minimize ground loops lead resistance drops since regulator external sense lead. Bypassing output also recommended. FIGURE 2-STANDARD APPLICATION
wire lengths, output load capacitance large. input bypass capacitor should selected provide good high-frequency characteristics insure stable operation under load conditions. 0.33 larger tantalum, mylar, other capacitor having internal impedance high frequencies
common ground required between input output voltages. input voltage must remain typically above output voltage even during point input ripple voltage. required regulator located appreciable distance from power supply filter. improves stability transient response.
