Principle of Operation

The TPS7A8101EVM-093 is a low power, high-efficiency evaluation board based on linear voltage regulator. It is composed of the TPS7A8101 linear voltage regulator and other components. The TPS7A8101 is a low-volatility low-dropout (LDO) regulator. It is a well-designed, single-channel LDO device that supports a wide range of voltage from 0.3V to 8V and current up to 3A. The TPS7A8101 is designed to combine low quiescent current and high output current accuracy. The TPS7A8101 operates in two modes: active and sleep. The LDO’s input is applied to the MPP pin. When the input voltage is above the UVLO, the TPS7A8101 operates in the active mode and the output voltage is regulated to the setpoint. The output voltage is adjusted by using the sensing voltage between the EN and ADJ pins. In the sleep mode, the TPS7A8101 will greatly reduce the quiescent current of the load. The board is composed of several components, which include the power supply, voltage regulator, resistors, capacitor, and diode. The power supply is used to provide a stable and regulated voltage input to the board. The voltage regulator is then used to regulate the input voltage and provide a stable voltage output. The resistor is used to adjust the output voltage. The capacitor is used to filter out noise from the output and stabilize the output voltage. The diode is used as a protection against back current.

Conclusion

The TPS7A8101EVM-093 is a low-power, high-efficiency evaluation board based on linear voltage regulator. It offers adjustable output voltage, adjustable current limit and adjustable input and output protections and monitoring. The board is suitable for various applications including industrial, automotive, battery powered, and outdoor/mobile equipment. It has been designed to provide designers with a solution for their power management needs. It is a well-designed device that combines low quiescent current and high output current accuracy. The TPS7A8101 is designed for providing reliable and efficient power for medical, instrumentation, communications, and consumer electronics.
