This user guide is intended to demonstrate use of the Pspice model for the TPS7H1101A-SP low-dropout
linear regulator. Instructions on how to import the unencrypted model netlist into Cadence Pspice
also provided. The first half of the guide outlines the modeled parameters and the second half of the guide
addresses how to simulate the modeled parameters.
