TLV755P: 5V on Enable pin under my customer's condition

Part Number: TLV755P

Hi,

When VIN=3.3V, Vout=2.5V on TLV75525P, my customer controls "EN pin" using 5V line.

Does he has any issue to use 5V input on enable pin under above condition?

 

Also, when VIN=VOUT=0V (No power), it is possible for him to control "EN pin" using 5V.

Does he has any issue to use 5V input on enable pin under above condition?

Please advise us.

Thanks and best regards,

M.HATTORI.

  • Hi Hattori-san,

    There is no concern with having Ven>Vin with the TLV755P. In our newer LDOs we have strived to make sure the sequencing of Vin and Ven can be independent without concern. Usually the best way to assess this is to check the abs max for the EN pin and ensure Ven does not have a min/max value that is relative to Vin.
