Normal Operation
UVLO = 1V
VIN - SENSE = 150 mV or VIN < R
V
OUT = VIN, Normal operation
Disabled, OUT = 0V, SENSE = VIN
CL = GND
CL = VDD
VIN-SENSE stepped from 0 mV to 80
mV
Enabled, SENSE = OUT
Disabled, OUT = 0V
Enabled, OUT = 0V
VIN - SENSE, CL = GND, CB = GND
CB = GND
VIN - SENSE, CL = GND, CB = VDD
CB = VDD
VIN - SENSE stepped from 0 mV to 150
mV, time to GATE low, no load
