ADP2108AUJZ-3.0-R7 generates 3.36 volts and it looks like it's hot

Hi.

I'm designing a prototype with the ADP2108-3.0V.

Without load, I verified that the output voltage was equal to the input (5.0V).

Somewhere, in the data sheets I read that when the load current is zero, the device doesn't switch, so I decided to place a load of 330 ohms. Then the voltage that appears is 2.25V.

I have placed a load of 100 ohms and the voltage drops to 1 volt with a lot of noise, whereas when it is 2.25 V the noise is almost zero.

I have also read similar problems in other threads, so I put the input capacitor of 4.7 uF next to pin1 of the regulator and it seems that the problem was solved.

But when measuring the voltage on the 330 resistance I noticed that the voltage is 3.36 volts and the regulator is somewhat hot.

I have checked the PCB and it seems that there is no type of short circuit, the only load is the resistance.

Any comment or idea is welcome.
