SG79xxG

SG79xxA / SG79xx TM ® Negative Fixed Voltage Regulator P RODUCT D ATASHEET DESCRIPTION The SG79xxA/SG79xx series of negative regulators offer self-contained, fixedvoltage capability with up to 1.5A of load current and input voltage up to -30V. With a variety of output voltages this regulator series is an optimum complement to the SG7800A/SG7800 positive three terminal regulators. These units feature a unique band gap reference which allows the SG79xxA series to be specified with an output voltage tolerance of ±1.5%. The SG79xxA versions also offer much improved line regulation characteristics. All protective features of thermal shutdown, current limiting, and safe-area control have been designed into these units and since these regulators require only a single output capacitor (SG79xx series) or a capacitor and 5mA minimum load (SG120 series) for satisfactory performance, ease of application is assured. Although designed as fixed-voltage regulators, the output voltage can be increased through the use of a simple voltage divider. The low quiescent drain current of the device insures good regulation when this method is used. These devices are available in hermetically sealed TO-257 (both case grounded ‘G’ and isolated ‘IG’), TO-3, TO39 and LCC packages.
