TLV702-Q1: Will the output be pulled up higher than 3.3V in this case and why?

Part Number: TLV702-Q1

Hi

Is the LDO output able to maintain the 3.3V if the output is series with a voltage source in this case? See above picture for reference. Thanks!

  • HI Ted,

    The LDO does not have the ability to sink current. The block diagram below shows that there is a parasitic diode that will conduct VOUT to VIN whenever VOUT is larger than VIN.

    What is the application where you would be putting 5V at the output of the LDO? Does this answer your question?

    Regards,
