General Description

The TS1583 family is a positive adjustable and fixed voltage regulator developed to provide 1.5A 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 device failure under the worst operation condition

with both Thermal Shutdown and Current Fold-back.
