Lae791p Rev: 20 Schematic Better

Earlier revisions (Rev 1A, Rev 5, Rev 12) had different pin configurations, compensation networks, and feedback loops.

The keyword "lae791p rev 20 schematic better" exists because the repair community is tired of wasting hours on bad data. A mediocre schematic gives you a map with missing roads. A "better" schematic gives you GPS with traffic updates. lae791p rev 20 schematic better
