Other Parts Discussed in Thread: DEM-SOT223LDO,
My customer is using TPS73701DCQR.
Customers designed with peripheral component constants described below.
Phenomenon①:There was a device whose output voltage dropped by about 0.5V when the load by 200mA.
Phenomenon②:However, if it is confirmed by the following constants, the output voltage does not decrease.
We confirmed the target sample on TI's general purpose EVM "DEM-SOT223LDO", but the same phenomenon has occurred.
(I guess customer is no error in pattern design from this result.)
<Comment on peripheral component constants>
· I think that customers designing at peripheral capacitors as specified.
· Although there is no description at datasheet of the feedback resistor for the 4.5 V setting, it is the recommended range of the output voltage setting.
<Question>
From this situation, can you tell me what is caused by (as you can guess)?
Best regards,
Masumi Sekiguchi
