DESCRIPTION
The IP140MA and IP78M00A series of voltage
regulators are fixed output regulators intended for
local, on-card voltage regulation. These devices are
available in 5, 12, and 15 volt options and are
capable of delivering in excess of 500mA over
temperature.
The A-suffix devices are fully specified at 0.5A,
provide 0.01% / V line regulation, 0.3% / A load
regulation, and ±1% output voltage tolerance at room
temperature. Protection features include safe
operating area, current limiting and thermal
shutdown.
