Hi,
i have trouble working with the TPS7A2055PDBVR LDR regulator. I want to use this chip to generate a 5.5V output voltage from a 6 V source.
In my design i have an output cap with 22uF and an input cap >1 uF.
The load is connected with a PMOS. If to mosfet is open, the output voltage is around 5.3V with an input voltage ov 6.00V. This is not as expected but could work.
As soon as i connect the load (max 50mA), the voltage drops to below 4 V.
The EN-Pin is connected to the input voltage.
Can you explain this behavior?
