Hi,

what are the coarse resistance values of R1, R2 internal resistors for LM5165 fixed output voltage version (3.3V)?

Thanks and best regards,

Hi Kohl,

The VOUT pin input current has a spec of 3.9uA for the 3.3V option.

This means the internal resistor: R1 = 1.22/3.9uA = 320Kohms approximately

R2 = 525Kohms (approx)

Regards,
Gautam
