Introduction to UC385EVM-207 Evaluation Board

The UC385EVM-207 Evaluation Board is a low-voltage linear voltage regulator designed by Texas Instruments to evaluate the performance of their UC385 series of low-drop out (LDO) regulators. The Board is meant to provide users with an easy way to test the maximum input voltage and power dissipation capability of the UC385 device under varying conditions. The user can use the Board in both single-output and multiple-output applications.

Application Field

The UC385EVM-207 can be used in a variety of applications including applications requiring single-supply operation, battery-powered systems, microprocessors and signal amplifiers. The evaluation Board is useful for a wide variety of consumer and industrial applications.In consumer applications, the UC385EVM-207 can be used for video or audio systems, hand-held computers, notebook computers, data communications, test instrumentation, consumer appliances and automotive applications. The Board can also be used in industrial applications such as power supplies, motor control, motor speed and position control, and process monitoring and control.

Working Principle

The UC385EVM-207 has an integrated circuit (IC) in its design known as a UC385 LD0 regulator. This IC contains an operational amplifier (op-amp), a voltage reference, two transistors, two resistors and two capacitors.The voltage reference acts as a reference voltage for the circuits which are connected to the LD0. The op-amp, transistors, and resistors control the feedback loop that ensures the output voltage is precisely regulated. The two capacitors are used to store energy and stabilize the output voltage of the circuit.The UC385EVM-207 works by taking an input voltage and regulating it to a precise output voltage. The input voltage determines the output voltage and output current of the Board. The output voltage and output current of the Board are limited by a maximum input voltage and by a maximum power dissipation limit.The input voltage may vary within the allowable range, but the output voltage remains constant, allowing for stable operation. When the input voltage reaches the maximum allowed by the design, the Board will shut down and the output voltage will remain constant until the input voltage is safely reduced.

Conclusion

In conclusion, the UC385EVM-207 Evaluation Board is a low-voltage linear voltage regulator designed to evaluate the performance of the UC385 series of LD0 regulators. The Board is designed for use in a wide variety of consumer and industrial applications where a reliable regulated voltage is required. The Board works by taking an input voltage, regulating it to an output voltage, and limiting the output voltage and current by a maximum power dissipation limit and maximum input voltage limit.
