Hi team, 

Could you confirm whether TPS7B81-Q1 survives through ISO 7637-2 pulse 5b test or not?

Regards,
Ochi

    Hi Ochi, 

    Normally there will be a TVS at the system input, and  ISO 7637-2 pulse 5b is a system-level test. The voltage directly applied at the input of the LDO will be clamped to the TVS voltage, as long as it's under the maximum 45V, the LDO should pass the test without a problem.
