Product Summary

The SG7912AT/883B negative regulator offers self-contained, fixed-voltage capability with up to 1.5A of load current. With a variety of output voltages and four package options SG7912AT/883B is an optimum complement to the SG7800A/SG7800, SG140 line of three terminal regulators. These units feature a unique band gap reference which allows the SG7912AT/883B to be specified with an output voltage tolerance of ±1.5%. The SG7912AT/883B also offers 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 (SG7900 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, especially for the SG120 series. The SG7912AT/883B is available in hermetically sealed TO-257, TO-3, TO-39 and LCC package.
