| SG140A/SG140 POSITIVE FIXED VOLTAGE REGULATOR DESCRIPTION The SG140A/140 series of positive regulators offer self contained, fixed-voltage capability with up to 1.5A of load current and input voltage up to 50V (SG140A series only). These units feature a unique on-chip trimming system to set the output voltages to within 1.5% of nominal on the SG140A series and 2.0% on the SG140 series. The SG140A 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 (isolated), TO-3, TO-66, and TO-39 power packages. FEATURES * Output voltage set internally to 1.5% on SG140A * Input voltage reange to 50V max. on SG140A * Two volt input-output differential * Bandgap reference voltage * Excellent line and load regulation * Foldback current limiting * Thermal overload protection * Voltages available - 5V, 12V, 15V * Voltages Not Recommended For New Designs - 6V, 8V, 18V, 24V HIGH RELIABILITY FEATURES - SG140A/140 Available to MIL-STD - 883 Radiation data available LMI level "S" processing available SCHEMATIC DIAGRAM 2/90 Rev 1.4 6/97 Copyright 1997 1 11861 Western Avenue Garden Grove, CA 92841 (714) 898-8121 FAX: (714) 893-2570 LINFINITY Microelectronics Inc.

RECOMMENDED OPERATING CONDITIONS (Note 2) Operating Junction Temperature Range: SG140A/140 .................................................. -55C to 150C Note 2. Range over which the device is functional. CHARACTERISTIC CURVES 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 inputoiutput 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.
