This series of fixed negative voltage integrated circuits Voltage regulators are designed for a wide range of applications. These include on-card regulations for elimination of sound and distribution problems associated with single point arrangement. In addition, they can be used to control series-pass elements to create high-voltage voltage control circuits. One of these controllers can supply up to 100 mA output current. The internal current limiting and thermal shutdown functions essentially make them immune to overload. When used as a replacement for a combination of zener diode and resistor, these devices can provide efficient power.
