Hello,
My customer is using the TPS71733QDRVRQ1 with VIN=5.5V and VOUT=3.3V.
They have some questions about the device.
Q1) Is there a shutdown function according to input voltage changes? If so, what is the input voltage for shutdown under the above user conditions?
Q2) What is the current in the internal diode?
Q3) How many voltage output modes can the user select from this device?
Thank you.
Hello JH,
1. 
depending on what load current the device is supporting, the input must be VDO + 3.3V.
2. Do you mean the current rating of the ESD protection diode? We typically do not recommend more than 5% of the rated current if there is a reverse current condition.
3. The specific device you chose is only a 3.3V output [TPS71733QDRVRQ1]. The product is offered in 10 voltage options:
If you chose an adjustable version, you can set it within the rated range:
Best,
Juliette
