SG78xx A/78xx Positive Fixed Voltage Regulator Description The SG78xx A/SG78xx series of positive regulators offer self-contained, fixed-voltage capability with up to 1.5 A of load current and input voltage up to 50 V (SG78xx A series only). These units feature a unique on-chip trimming system to set the output voltages to within ±1.5% of nominal on the SG78xx A series with ±2.0% on the SG78xx series. The SG78xx A versions also offer much improved line and load regulation characteristics. Utilizing an improved bandgap reference design, problems such as drift in output voltage and large changes in the line and load regulation, that are normally associated with the Zener diode references have been eliminated. 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 small output capacitor for satisfactory performance, ease of application is assured. Although designed as fixed-voltage...
