Connect the test setup as shown in Figure 1.
Apply supply voltage Vin = 1.5 V
Apply supply voltage Vbias = 5.0 V
Apply Iout = 10 mA load.
Check that Vout is 1.2 V
Increase Iout load current to 3.0 A
Check that Vout is 1.2 V
Decrease Iout load current to 10 mA
Check that voltage on PG output VPG is 5 V
Decrease Vin voltage to 0.9 V
Check that voltage on PG output VPG < 0.1 V
Power down the load
Power down Vin and Vbias supply
