MP8126DF TSSOP-16

The MP8126 is a voltage regulator designed to
provide efficient, low-noise power to a satellite
receiver’s RF LNB (Low Noise Block) converter.
It connects using a coaxial cable through a link
that is compatible with the European
EUTELSAT specification (DiSEqC) 1.x that
receives instructions from a dedicated controller.
The MP8126 integrates a current-mode boost
regulator followed by a tracking linear regulator.
The boost regulator provides a clean and quiet
power source that will not contaminate the lownoise RF signal as it is down-converted to the
receiver. The tracking linear regulator protects
the output against overloads or shorts.
