The TPS7B6850QPWPRQ1 is an adjustable, low-dropout linear regulator that provides excellent performance features, such as fast transients, low output noise, high PSRR and minimal junction-temperature excursion. It provides a regulated output voltage up to 10 A. The output voltage is adjustable using two external resistors. It can also be used in current limit mode using an external resistor.
Working Principle
The TPS7B6850QPWPRQ1 consists of an adjustable series voltage regulator, control circuitry and current limit circuit with a shutdown control. The series voltage regulators regulate the output voltage by sensing the regulation voltage between the output of the series regulator and the feedback voltage, and adjusting the series regulator current to maintain the nominal output voltage. Detection of the output change is done by a fraction of the output current being routed to the current limit circuit and feedback as a percentage of the output voltage regulation. The control circuitry senses the regulation voltage and adjusts the series regulator current to maintain the nominal output voltage.
The current limit circuit monitors the output current and provides thermal protection by limiting the output current to a specified value. The output of the current limit circuit is connected to the control circuit in order to provide the thermal protection. The shutdown control circuit provides disabled or enabled condition of the device. When the device is disabled, the output voltage is reduced.
