3A Dual Input LDO
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.
Features
● Very low dropout voltage: 700mV @3A
● Output current up to 3A
● Low current Consumption
● High Accuracy Output Voltage: ±1%
● Fast transient response
● Remote sense
● Internal current limit
● Thermal shutdown protection
Applications
● High efficiency linear regulator
● Post regulators for switching supplies
● Advance graphic card
● Adjustable power supply
