The SG120 series is a type of negative voltage regulator that offers self-contained, fixed-voltage capability with up to 1.5A of load current. It comes with a variety of output voltages and four package options, making it an ideal complement to the SG7800A/7800/120 line of three-terminal regulators. All protective features such as thermal shutdown, current limiting, and safe-area control have been incorporated into these units. These regulators require only a single output capacitor or a capacitor and a minimum load of 5mA for satisfactory performance, ensuring ease of application. Although designed as fixed-voltage regulators, the output voltage can be increased using a simple voltage divider. The low quiescent drain current of the device ensures good regulation when this method is used, especially for the SG120 series. By utilizing an improved Bandgap reference design, issues commonly associated with zener diode references, such as output voltage drift and significant changes in line and load regulation, have been eliminated. These devices are available in TO-257 (hermetically sealed TO-220), both isolated and non-isolated, as well as TO-3, TO-39, and TO-66 power packages.
