8.4.1 Device Functional Mode Comparison

Table 8-1 shows the conditions that lead to the different modes of operation. See the Electrical Characteristics table for parameter values.

Table 8-1 Device Functional Mode Comparison
OPERATING MODE PARAMETER
VIN VEN IOUT TJ
Normal operation VIN > VOUT(nom) + VDO and VIN > VIN(min) VEN > VEN(HI) IOUT < IOUT(max) TJ < TSD(shutdown)
Dropout operation VIN(min) < VIN < VOUT(nom) + VDO VEN > VEN(HI) IOUT < IOUT(max) TJ < TSD(shutdown)
Disabled
(any true condition disables the device)		 VIN < VUVLO VEN < VEN(LOW) Not applicable TJ > TSD(shutdown)
