7.4.1 Device Functional Mode Comparison

The Device Functional Mode Comparison table shows the conditions that lead to the different modes of operation. See the Electrical Characteristics table for parameter values.

Table 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)
