| COM150T (COTS) COMMERCIAL OFF-THE-SHELF 3.0 AMP POSITIVE ADJUSTABLE VOLTAGE REGULATOR IN TO-257 PA C K A G E Three Terminal, Adjustable Voltage, 3.0 Amp Precision Positive Regulator In Hermetic JEDEC TO-257AA Package FEATURES * * * * Isolated Hermetic Package, JEDEC TO-257AA Outline Reference Voltages Set To 2% Built-In Thermal Overload Protection Short Circuit Current Limiting DESCRIPTION These three terminal positive regulators are supplied in a hermetically sealed isolated, metal TO-257 package. All protective features are designed into the circuit including thermal shutdown, current limiting and safe-area control. With heat sinking, they can deliver over 3.0 amps of output current. These units feature 2% initial voltage tolerance, 0.35% load regulation and .01% line regulato. in ABSOLUTE MAXIMUM RATINGS @ 25C Input - Output Voltage Diff r n i l........................................ +35 V eeta Operating Junction Temperature Range........................ - 55C to + 150C Storage Temperature Range ................................. - 65C to + 150C Typical Power/Thermal Characteristics: Rated Power @ 25C TC ............................................................... 25 W TA ................................................................ 3 W Thermal Resistance .............................................. 4.2C/W oJA .............................................................. 50C/W a www..com 8 09 R0 www..com www..com 33 - 1 .
