TPS769: TPS76950 Oscillates

Part Number: TPS769
Other Parts Discussed in Thread: TPS767,

Hi all I am using TPS76950 Fixed 5V regulator in my system which has following powerparameters

Input Voltage: 6V

Output voltage: 5V

Peak current consumption: 70mA

Constant current current consumption: 3mA

I have made the regulator circuit in the following way

and post wiring the output oscillates and the waveform look like this:

I have a 1uF decoupling on the input and a 0.1uF, 1uF &  100uF electrolytic on the output.

The part which is very funny is that each board had different behavior.

Urgent help will be appereciated.

Let me know if more information is needed from my end

Regards
