TS1583

1.5A Dual Input Low Dropout Positive Voltage Regulator

Low Dropout Voltage 0.7V max.

Fix or Adjustable Output

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.
