Analog Devices μModule Regulator : Why is the simulation result different even if I download the LTspice sample circuit for LTM4700 from the Analog Devices HP and use the same resistor and capacitor constants as in the datasheet?

LTspice power management

The downloaded LTM4700 LTspice circuit contains settings to be placed in NVM/EEPROM. I'm assuming its settings are different. SPICE does not have a function to set registers directly, so the LTM4700 model has additional parameters for SpiceLine and SpiceLine2. If you CTL + right click on the LTM4700 symbol, the Attribute Editor will pop up and you can check SpiceLine/SpiceLine2.
