TS1581
5A Dual Input Low Dropout Positive Voltage Regulator
Low Dropout Voltage 0.7V max.
Fix or Adjustable Output
General Description
The TS1581 family is a positive adjustable and fixed voltage regulator developed to provide 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 TS1581
series are designed to prevent device failure under the worst operation condition with both Thermal Shutdown and
Current Fold-back.
Features
Very low dropout voltage: 700mV @5A
Output current up to 5A
Low current Consumption
High Accuracy Output Voltage: +/- 1%
Fast transient response
Remote sense
Internal current limit
Thermal shutdown protection
