TPS79730-EP: Non-space rated LDO to survive 5mRad

Part Number: TPS79730-EP

Hi Guys,

Good day.

Our customer is looking for a catalog or automotive LDO type that would be more likely to survive 5Mrad high dose rate irradiation by Co60 gamma source And has a relatively thin metal oxide layer.

His supply is 24VDC and he needs a low noise LDO to go from 5V to 3V. I was not able to find any in our database that fits his requirements except for the -EP variants of LDOs like TPS79730-EP.

Do you have anything at least closest to what he needs that he can consider to evaluate?

Thanks in advance.

  • Hi Art,

    We don't characterize or prepare our LDOs for radiation resiliency. There may be one out there that can meet their requirement but we have no way of gauging it. 

    Regards,
