Abstract: With the wide application of low dropout linear regulator (LDO) devices in aerospace and other fields, the index of its anti single particle ability is becoming more and more important. In order to realize the real-time monitoring of the single event effect of LDO devices under different particles, a test method for the single event effect of LDO devices under different particles is designed, and a high-speed, multi-channel data acquisition, measurement and control system is built. The system takes the NI industrial computer as the core, and can measure the signal frequency up to 60 MHz through the PXIe bus and external program-controlled instruments. The system supports remote data transmission and can monitor the power consumption performance of LDO devices under single-event irradiation in real time to meet the requirements of single event effect test, and provide data reference for the experimental research of single event effect of LDO devices.
