STMicroelectronics STEVAL-QUADV01 Evaluation Board

STMicroelectronics STEVAL-QUADV01 Evaluation Board is based on L6981, L7983, ST1PS03 monolithic step-down regulators, and ST730 LDO regulators. The L6981 module delivers up to 1.5A DC current, and the L7983 and ST730 module provides up to 300mA DC current. The ST1PS03 synchronous monolithic step-down regulator delivers up to 400mA DC current. This evaluation board can be used in a wide range of applications due to a combination of input voltage and output current ranges and embedded features. Typical applications include DC-DC converters and linear voltage regulators.
