BDxxFD0 series
Description
The BDxxFD0 series are low-saturation regulators. The
seriesoutput voltages are Variable, and fixed type.
These series have a built-in over-current protection
circuit that prevents the destruction of the IC due to
output short circuits and a thermal shutdown circuit that
protects the IC from thermal damage due to overloading.
Features
Output current capability: 2A
Output voltage: Variable, Fixed
