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.
