Preliminary Data Sheet OM183-5, 12, 15NM OM185-5, 12, 15NM OM184-5, 12, 15NM OM186-5, 12, 15NM SURFACE MOUNT LOW DROPOUT POSITIVE FIXED VOLTAGE REGULATORS Three Terminal, Low Dropout, Positive Fixed Voltage, 7.5A, 5A, 3A And 1.5A Regulators FEATURES • • • • • • • Hermetic Surface Mount Package Operates Down To 1V Dropout, 1.5V @ Max. Current .015% Line Regulation .01% Load Regulation 1% Reference Voltage Electrically Equivalent To LT1083, 84, 85, And 86 Available Hi-Rel Screened DESCRIPTION These three terminal positive fixed voltage regulators in surface mount packages are designed to provide 7.5A, 5A, 3A, and 1.5A with higher efficiency than conventional voltage regulators. These devices are designed to operate to 1 Volt input to output differential and the dropout voltage is specified as a function of load current. These devices are ideally suited for Hi-Rel applications where surface mount, small size, hermeticity and high reliability are required.
