The STEVAL-LDO001V1 evaluation board is equipped with the latest in linear voltage regulator technology. It is based on the ST LD1117V33, a 3.3V low drop-out linear voltage regulator. The device features a wide input voltage range of 4.5V to 20V, and delivers an adjustable output voltage up to 12V. It has an impressive power of up to 1.5A, and very low dropout voltage of 0.3V at full load current. The ultra-low quiescent current ensures very low power consumption when the output is not required. The board features over-temperature, over-current and reverse voltage protection to ensure safe operation.

The working principle of the STEVAL-LDO001V1 evaluation board is based on the regulation of the output voltage, which is achieved by controlling the current passing through the regulating pass transistor. The current through the pass transistor is in turn controlled by a feedback loop that monitors the output voltage. A comparison is made between the measured output voltage and a reference voltage, and the difference determines the current through the pass transistor. This current is adjusted until the output voltage equals the reference voltage, at which point the output voltage is regulated at the desired level.
