SG120-15R

SG120 NEGATIVE FIXED VOLTAGE REGULATOR DESCRIPTION The SG120 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/ 7800/120 line of three terminal regulators. 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 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. 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.

Both C1 and C2 should be low E.S.R. types such as solid tantalum. If aluminum electrolitics are used, at least 10 times values shown should be selected. 3. If large output capacities are used, the regulators must be protected from momentary input shorts. A high current diode from output to input will suffice.
