Other Parts Discussed in Thread: TPS7A91, TPS7A80
Hi,
I am using TPS73701 as 3.3V LDO in the application.
Cin on Vin is 1uF and Cout on Vout is 10uF and 1nF is applied.
When Vin is supplied from power supply(Vout=3.6V, Imax set to 2A, Iout = 200mA) , LDO is oscillating which make multi tone to single tone RF signal.
Have you seen the issue on it?
By putting big capacitor in the output of Power supply, it can be disappeared. But it looks unusual.
I attached the application and measurement.
