Evaluation Boards – Linear Voltage Regulators

Linear voltage regulators are key components in a wide range of systems, from computers and consumer electronics to automotive, medical and other industrial applications. An evaluation board helps engineers in their design efforts by verifying the accuracy of the voltage regulator’s operation and compatibility with a particular system.The TPS74301EVM-118 is such an evaluation board dedicated to the TPS74301 voltage regulator, a low dropout (LDO) regulator specifically designed for applications requiring high precision: it features an output voltage accuracy of ±1.0% over a wide VIN and temperature range. The board has multiple voltage settings, enabling a wide output voltage range of 0.75 V to 5.5 V, with peak currents up to 1.5 A, and up to 120 mA in ultra low-noise operation mode.The TPS74301EVM-118 evaluation board enables engineers to quickly evaluate the TPS74301 voltage regulator’s features and performance. Built around an 8-Ld SOT-223 package, the board is a high-efficiency solution that provides many advantages over traditional voltage regulators. It features a wide input voltage range (3 V to 24 V) and dropout voltage (595 mV at a load current of 100 mA) which translates into higher power savings in certain applications. Inside the evaluation board, the voltage regulator is connected to an array of voltage dividers to monitor both input and output voltages. Besides, it’s integrated with a two-phase current source and a thermal protection circuit to guard against current overload or thermal runaway.The evaluation board also includes a diagnostic LED and a power-on reset circuit to ensure reliable start-up behavior and constant operating parameters set by the regulator. In addition, the board is equipped with adjustable voltage setting jumpers and thermal shutdown protection that allows the LDO to be configured to the desired voltage level and to have its operating temperature range be adjusted to the particular application.In order to evaluate the TPS74301 voltage regulator, the TPS74301EVM-118 evaluation board needs to be connected with an isolated, multi-output (6V-9V) DC supply. The board’s input voltage range is from 3 V to 24 V, therefore the voltage supply should be adjusted to the desired operating voltage. The evaluation board should also be connected to an oscilloscope or data acquisition system, for detailed measurements and analysis of the voltage regulator’s operation.The evaluation board is intended for applications such as power management in portable devices, cell phones, notebook computers, modems and MP3 players, and any circuit that requires very low dropout voltage, low noise performance, and precise regulation of output voltage. Moreover, the board can be useful for evaluation of economical power supply solutions needed in industrial and medical equipment.In summary, the TPS74301EVM-118 evaluation board enables engineers to examine the features and performance of the TPS74301 voltage regulator quickly and efficiently. It features a wide input voltage range, a low dropout voltage, a current source and thermal protection circuit, along with adjustable voltage setting jumpers and power-on reset circuitry. Enabling a wide range of applications in consumer electronics, industrial and medical equipment, the TPS74301EVM-118 evaluation board is an invaluable tool for engineers conducting evaluation and verification of the TPS74301 voltage regulator.
