TINA/Spice/TPS7H1101-SP: How to simulate the Bode diagram of LDO with TIAN-TI

Hi,

I have a simulation model of the LDO TPS7H1101-SP on your official website.

As shown above, the simulation model has transient simulation and output impedance simulation.

I want to simulate the bode diagram of the LDO's open-loop transfer function. A small amplitude (100mV) sine wave of sweep frequency (100Hz~1MHz) is injected into the R7 (50 ohm resistor), and then the gain and phase ratio of each signal at both ends of the resistor are compared.

However, I don't know how to take this simulation?

Or is this a transient simulation, how do I want to get a bode diagram, is it necessary to replace the LDO with an average model? How can I import the average model into TIAN-TI?
