The Texas Instruments TPS728185315EVM267 is an evaluation module (EVM) specifically designed to enable users to evaluate the performance of the TPS728185315 precision low-dropout regulator (LDO). This high-performance device is suitable for a wide range of applications, from rail-to rail supplies, linear generators and battery backed low-noise power supplies. It features a programmable control loop and is available in either an integrated or a stand-alone version.

The TPS728185315EVM267 is classified as a linear voltage regulator. A linear regulator is basically an electronic device that provides a stable output voltage that is independent of the input voltage. The circuit works by constantly monitoring the output voltage and adjusting it to its preset value by varying the current through an integral sensing resistor. It is so called because it operates with a constant voltage drop across the internal elements.

The TPS728185315EVM267 is capable of regulating input voltages from as low as 2.7V to as high as 18V. Its low dropout voltage improves efficiency and enables it to provide stable, low noise output voltages. Its accuracy is guaranteed to stay within ±2% across load and temperature variations, and it features an excellent line and load transient response. The device also features built-in current, thermal, and overvoltage limits.

The device can be used to control a number of different applications, such as microprocessors, FPGAs, DSPs, mixed-signal communication systems, microcontrollers, power management, digital signal conditioning, and analog non-linear loads. The device is also used for power levels above the capacity of multiple-output regulators, providing a clean and efficient solution for many different types of systems.

The TPS728185315EVM267 has a relatively simple working principle. It generally operates in three distinct phases, namely the turn-on phase, the voltage regulation phase, and the turn-off phase. During the turn-on phase, the device draws a large current until the required output voltage is reached. The voltage regulation phase begins once the desired output voltage is reached and the device starts to draw a much smaller current. Finally, during the turn-off phase, the device draws a slightly larger current before completely shutting off.

In summary, the TPS728185315EVM267 is a highly reliable and efficient linear voltage regulator that is suitable for a wide range of applications. It features low drop out voltage, excellent accuracy, and built-in current, thermal, and overvoltage protection, making it an ideal choice for many power management systems. It operates in three distinct phases and can provide stable, low-noise output voltages despite variations in input voltage and load.
