About the Vin voltage at startup for MC34704.

Dear all,


We monitor VIN and VOUT5 of MC34704.


When the Vin voltage is remained about 0.2V, VOUT5 is output at Vin startup.
However, when the Vin voltage is remained about 0.3V, VOUT5 isn't output even if Vin stands up.

Please see attached file.


I understand that the remains voltage shouldn't exist on Vin at startup.
Is my understanding right?


Is the remains voltage defined?
(Is the allowed remains voltage defined?)


Best Regards,
