I am designing a power supply where I am using a voltage regulator LP2951 and a digital potentiometer DS1809. I found the symbol in DK_regulator.obj for LP2951 but the spice model(*.lib file) is missing. As far as DS1809 is concerned, I have nothing. I searched for a while and I think it's possible to do a spice model with pspice using the datasheet. Should I just enter the data in the sheet or is there a spice model out there that I have to follow? Please answer ASAP. Thank you.
