I have a problem with TPS7A5201 layout.
Schematic is attached. Input voltage is 4.2V and output voltage is set with R13 and R14 to 3.8V.
If layout is not loaded works good, I measure stable 3.8V on output.
But if I add load 500mA, output voltage drops down to stable 3.5V. If I add 1A load output voltage drops to 3.2V .... If I add full load 2A output voltage is 2.5V.
I tried to add larger input capacitors 3x 22uF and output capacitors 3x22uF but the problem remains.
