Evaluation Boards - Linear Voltage Regulators

LP3996SD-3333EV is an evaluation board for linear voltage regulators. It is designed to provide a scalable platform to evaluate circuit performance with minimal power consumption, wide range of output voltage options, and phenomenal thermal performance.

Applications

The LP3996SD-3333EV is suitable for a wide range of applications, including automotive, LAN, telecom, consumer electronics, industrial, and medical. The given device can be used as a voltage regulator for high-speed, low-power applications. In addition, the adjustable output voltage ability of the board allows for the desired voltage level to be set.

Working Principle

Working principle of LP3996SD-3333EV is based on linear voltage regulation. In linear regulation, an error amplifier compares the output voltage to a reference voltage. When the output voltage exceeds the reference voltage, the error amplifier turns on the series pass device, which limits the output voltage. When the output voltage is below the reference voltage, the error amplifier turns off the series pass device, allowing full current to pass through.

The direct connection of the error amplifier to the Vout pin means that there is no need for an external sense resistor or amplifier. This increases power efficiency of the device and also eliminates the need for extra components, resulting in a simplified design. The LP3996SD-3333EV board also features a built-in safety diode, enabling internal current protection as well as external devices.
