The TS1583 family is a positive adjus table and fix ed voltage regulator developed to provide 1.5 A with Higher efficiency than currently available devices . All internal circuit is designed to operate down to 700mV input to output differential and the dropout voltage is fully specified as a function of load current. Dropout voltage of the device is 100mV at light loads and rising to 700mV at maximum output current. A Second low current input is required to achieve this dropout. The TS1583 series are designed to prevent dev ice failure under the worst operation condition with both Ther mal Shutdown and Current Fold-back .
