Semelab Plc IP78M05ALCC4, IP78M15LCC4, IP78M12LCC4, IP78M12ALCC4, IP78M05LCC4 Datasheet

DESCRIPTION

The 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.

1) All characteristics are measured with a capacitor across the input of 0.22µF and a capacitor across the output of 0.1µF.
All characteristics except noise voltage and ripple rejection ratio are measured using pulse techniques (t

p

≤ 10ms, δ≤5%). Output

voltage changes due to changes in internal temperature must be taken into account separately.
