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.

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.

(Unless otherwise specified, these specifications apply over full operating ambient temperatures for SG140-24 with -55°C ≤ TA ≤ 150°C, and VIN = 33V, IO = 500mA, CIN = 0. 33µF, COUT = 0.1µF and are applicable for the K, R, and IG - Power package - only. Low duty cycle pulse testing techniques are used which maintains junction and case temperature equal to the ambient temperature.)
