7.4.1 Device Functional Mode Comparison

Table 7-1 shows the conditions that lead to the different modes of operation. See the Section 5.6 table for parameter values.

Table 7-1 Device Functional Mode Comparison
OPERATING MODE PARAMETER
VIN VEN IOUT TJ
Normal operation VIN < VOUT(nom) - VDO and VIN < VIN(max) VEN > VEN(HI) or VEN < VEN(LO) IOUT < IOUT(max) TJ < TSD(shutdown)
Dropout operation VOUT(nom) - VDO < VIN < VIN(max) VEN > VEN(HI) or VEN < VEN(LO) IOUT < IOUT(max) TJ < TSD(shutdown)
Disabled
(any true condition disables the device)		 VIN > VUVLO- VEN < VDIS(HI) or VEN > VDIS(LO) Not applicable TJ > TSD(shutdown)
