Analog System Lab Kit PRO
Simulate the circuits and compute the output characteristics, transfer
characteristics, and ripple rejection.
Input resistance (ohms)
Input voltage (V)
Perform the same experiment with the specialized IC for LDO from Texas Instrument
TPS7250 and compare the characteristics of both systems.

Take the plots of output characteristics, transfer characteristics and ripple rejection
from the Oscilloscope and compare it with simulation results.
Obtain the Load Regulation - Vary the load such that load current varies and obtain
the output voltage, see the point till where output voltage remains constant.
After that output will fall as the load current increases.
Obtain the Ripple Rejection - Apply the input ripple voltage and see the output
ripple voltage, with the input ripple voltage output ripple voltage will rise.
Obtain the Line Regulation - Vary the input voltage and plot the output voltage as
a function of the input voltage. Until the input reaches a certain value, the output
voltage remains constant; after this point, the output voltage will rise as the input
voltage is increased.
Calculate the output impedance.
