TS1582

3A Dual Input Low Dropout Positive Voltage Regulator

Low Dropout Voltage 0.7V max.

Fix or Adjustable Output

General Description

The TS1582 family is a positive adjustable and fixed voltage regulator developed to provide 3A 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 TS1582

series are designed to prevent device failure under the worst operation condition with both Thermal Shutdown and

Current Fold-back.
