MC79L00A Series. 100 ma Negative Voltage Regulators THREE TERMINAL LOW CURRENT NEGATIVE FIXED VOLTAGE REGULATORS

Transcription

1 00 Negative Voltage Regulators The negative voltage regulators are inexpensive, easytouse devices suitable for numerous applications requiring up to 00. Like the higher powered MC7900 Series negative regulators, this series features thermal shutdown and current limiting, making them remarkably rugged. In most applications, no external components are required for operation. The MC79L00A devices are useful for oncard regulation or any other application where a regulated negative voltage at a modest current level is needed. These regulators offer substantial advantage over the common resistor/zener diode approach.

5 Design Considerations The of fixed voltage regulators are designed with Thermal Overload Protections 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. 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 length, or if the output load capacitance is large. An input bypass capacitor should be selected to provide good APPLICATIONS INFORMATION highfrequency characteristics to insure stable operation under all load conditions. A 0.33 F 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. Bypassing the output is also recommended. +V in MC78LXX +V O 0.33 F 0. F Input C I * 0.33 F MC79LXX Output C O ** 0. F 0. F -V in MC79LXX -V O 0.33 F A common ground is required between the input and the output voltages. The input voltage must remain typically 2.0 V above the output voltage even during the low point on the ripple voltage. * C I is required if regulator is located an appreciable * distance from the power supply filter ** C O improves stability and transient response.
