DESCRIPTION

The IP140M/MA and IP78M00/A series of voltage

regulators are fixed output voltage 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 protection.
