OM183SC to OM186SR Positive Voltage Regulators Advancing the Semiconductor Industry Since 1972 MAIN FEATURES IMAGE SERVES AS A REPRESENTATION ONLY Operates down to 1V Dropout, 1.5V @ Max. Current .015% Line Regulation .01% Load Regulation 1% Reference Voltage Hermetic TO-257 and TO-258 Isolated Packages Electrically Equivalent to LT1083, 84, 85, and 86 DIMENSIONS (TOP: TO-258, BOTTOM: TO-257) ABSTRACT This family of three terminal positive adjustable voltage regulators are designed to provide 7.5A, 5A, 3A, and 1.5A with higher efficiency than conventional voltage regulators. The devices are designed to operate to 1 Volt input to output differential and the dropout voltage is specified as a function of load current. All devices are pin compatible with older three terminal regulators. Supplied in the easy-to-use hermetic metal TO-257 and TO-258 JEDEC packages, also supplied in a new surfacemount D2 package. These devices are ideally suited for Military applications where small size, hermeticity and high reliability are required.
