05/01 Rev 1.4 LIN F IN ITY Microelectronics Inc. Copyright  1997 11861 Western Avenue ∞ ∞ ∞ ∞ ∞ Garden Grove, CA 92841 POSITIVE FIXED VOLTAGE REGULATOR The SG7800A/SG7800 series of positive regulators offer self contained, fixed-voltage capability with up to 1.5A of load current and input voltage up to 50V (SG7800A series only). These units feature a unique on-chip trimming system to set the output voltages to within ±1.5% of nominal on the SG7800A series, ±2.0% on the SG7800 series. The SG7800A versions also offer much improved line and load regulation characteristics. 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. 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 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. Product is available in hermetically sealed TO-257, TO-3, TO39 and LCC packages. DESCRIPTION FEATURES

Values beyond which damage may occur. THERMAL DATA K Package: T Package: L Package: Note A. Junction Temperature Calculation: TJ = TA + (PD x θJA). Note B. The above numbers for θJC are maximums for the limiting thermal resistance of the package in a standard mounting configuration. The θJA numbers are meant to be guidelines for the thermal performance of the device/pc-board system. All of the above assume no ambient airflow. Note 3. Operation at high input voltages is dependent upon load current. When load current is less than 5mA, output will rise out of regulation as input- oiutput differential icreases beyond 30V. Note also from Figure 1, that maximum load current is reduced at high voltages. The 50V input rating of the SG140A series refers to ability to withstnd high line or transient conditions without damage. Since the regulator's maximum current capability is reduced, the output may fall out of regulation at high input voltages under nominal loading. FIGURE 1. PEAK OUTPUT CURRENT VS.
