The STEVAL-QUADV01 evaluation board is based on the L6981 (capable of delivering up to 1.5 A DC), the L7983 (capable of delivering up to 300 mA DC), the ST1PS03 (capable of delivering up to 400 mA DC) synchronous monolithic step-down regulators, and the ST730 (capable of delivering up to 300 mA DC) LDO regulator.

The combination of input voltage and output current ranges, and other embedded features makes the evaluation tool suitable for a broad range of applications.
