Hi
I am using TPS73201DCQR LDO.Input voltage is 3.3V and output voltage is 1.8V/200mA.When Resistor load.is connected It is observed that output drops below up to 1.72V and output ripple is arround 348mV peak-peak.
Test snap of actual waveform as per below.
Kindly suggest to resolve it
Thanks

Hi Ulhas,
It looks like the device is unstable when you apply the load. Can you try removing C301 and observe if the oscillations go away?
