8 Summary

The purpose of this report is summarize the SEE of the TPS73801-SEP under heavy ions. The data shows that the TPS73801-SEP is SEB and SEL free across the full electrical specifications and up to 43MeV-cm²/ mg with fluence of 10⁷ ions / cm². No SEL or SEB was observed, and the cross section for the SEL and SEB is shown to be on the order of 10^–8 cm² / device. See Section 6 for more details.

SETs were characterized at different output voltages and across the full load of the TPS73801-SEP. Only seven transients higher than 5% were observed on 16 runs. Those transients were all observed at V_OUT = 2.5V. Worst case for SETs deviations is observed at lower output voltages, and worst case transients response time are observed at light loads. The SET cross section is shown to be on the order of 10^–8 cm²/ device.
