Hello,
On my design, there is an I/O connected to this switch. I tried to disconnect the load, but there is no change.
Here is a snapshot of the TPS27081A output where;
C1 = 0.1uF
R1 = 10K
R2 = 1K
Output Resistor = none
Result: We have 1.8V level between 0V and 3.3V.
C1 = 0.1uF
R1 = 10K
R2 = 1K
Output Resistor = added
Result: We have 0.8V level between 0V and 3.3V.
C1 = open
R1 = 10K
R2 = 1K
Output Resistor = added
Result: We don't have this issue but the input voltage drops significantly.
