Product overview
Description
The LEO3910 is a positive adjustable voltage regulator housed into a Power-SO 20L slug-down package, which is able to provide in regulation a maximum output current up to 2 A.
It can operate over a large temperature range of -40 °C to +125 °C.
The LEO3910 is compliant with the ST-LEO-specification, dedicated specifications for space-ready rad-hard plastic products. This AEC-Q100-based specidfication offers a specific trade-off among footprint size savings, cost of ownership and quality assurance together with radiation hardness and a large quantity capability.
