Radiation effects on four common DC linear regulator topologies are investigated. Increasing total dose is shown to degrade converter regulation by degrading converter loop gain and phase response. SET response is characterized, and a mitigation technique is proposed. Shunt regulator topologies are found to be superior to series regulator topologies in terms of radiation tolerance.
