LP5907: PSRR of LP5907 at the set up : Vin=5v, Vout=3.3v, Iout=30mA, Cout=1u//270p.

Harry Ma

Part Number: LP5907

Hi Team

Can you help to provide the PSRR at the setup： Vin=5v, Vout=3.3v, Iout=30mA, Cout=1u//270p?

Frequency rang reach to 1MHz。

Thanks！

Hi Harry,

Let me see if we have any 3.3V samples and/or LP5907UV-3.3EVM to take this measurement. Please allow 1-2 business days.

Hi Harry,

Here are the results for PSRR with the given conditions.

The Green curve is Vin=5V, Vout=3.3V and Cout=1u||270p

Where the Yellow curve is Vin=5V, Vout=3.3V Cin =1uF and Cout=1u||270p since DS specifies this

Also, it is hard to tell, but I overlapped the results with our DS plot, and you can see that the results are close to each other:

Best,
