Abstract
The power supply is powered preferably from a conventional AC input line by way of an AC adapter and preferably provides DC voltage levels of -5 volts and +5 and +12 volts. The -5 volt level uses a single zener diode for regulation while the other two logic levels use voltage regulators each having pass transistor means associated therewith. The circuitry also includes current limiting circuitry and filter means.
