TINA/Spice/LM4040-N: All unencrypted SPICE-model only work with anode at GND

LM4041-N: LM4041-N

I am looking for more stable voltage regulater for temperature.

I am using LM4041DIM3-ADJ for 5V output from 8V input .between -20degC to +80degC. the datasheet said temperature coefficient is150ppm. This is a little bigger for my new application.

So, I am looking for more better performance regulator.

    Hi,

    Is there a reason you are using the LM4041 for a 5V output?

    I would use the fixed 5V output LM4040-N at 100ppm/C from -40C to 85C. This way there is no error from the resistors.

    Since you need better temperature drift. I would recommend the LM4050-N 5V variant 50ppm/C

    Or a series reference such as REF3450 6ppm/C
