Description

The SG120-15L series of negative regulators offer self-contained, fixed-voltage capability with up to 1.5A of load current. With a variety of output voltages and four package options this regulator series is an optimum complement to the SG7800A/ 7800/SG120-15L line of three terminal regulators. <BR><BR>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 or a capacitor and 5mA minimum load for satisfactory performance, ease of application is assured. Although designed as fixed-voltage regulators, the output voltage of SG120-15L can be increased through the use of a simple voltage divider. <BR><BR>The low quiescent drain current of the device insures good regulation when this method is used, especially for the SG120-15L series. Utilizing an improved Bandgap reference design, problems have been eliminated that are normally associated with the zener diode references, such as drift in output voltage and large changes in the line and load regulation These devices are available in TO-257 (hermetically sealed TO-220), both isolated and non-isolated), TO-3, TO-39 and TO-66 power packages.
