voltage regulator
Features
Operating input
voltage from 3 V to 12 V Adjustable output
voltage from 1.23 V to 9 V Low-dropout
voltage: 0.35 V @ IO = 400 mA Overtemperature protection Overcurrent protection Adjustable current limitation Inhibit (ON/OFF) TTL-compatible control Gold bonding Nickel/palladium/gold-lead-finished (NiPdAu), whisker-free RML <1% and CVCM <0.1% guaranteed outgassing 50 krad(Si) total ionizing dose SEL free up to 62.5 MeV.cm²/mg
T Compliant with ST-LEO-specification
Application
F Low earth orbit (LEO) applications A 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
Rup 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
Dspace-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.
