PRODUCTION DATA
Table 7-1 shows the conditions that lead to the different modes of operation. See the Electrical Characteristics table for parameter values.
| OPERATING MODE | PARAMETER | |||
|---|---|---|---|---|
| VIN | VADJ/EN | IOUT | TJ | |
| Normal operation | VIN > VOUT(Nom) + VDO and VIN ≥ VIN(min) | VADJ/EN > VIH | IOUT ≤ IOUT(max) | TJ < TSD(shutdown) |
| Dropout operation | VIN(min) < VIN < VOUT(nom) + VDO | VADJ/EN > VIH | IOUT ≤ IOUT(max) | TJ < TSD(shutdown) |
| Disabled (any true condition disables the device) |
VIN < VUVLO | VADJ/EN < VIL | Not applicable | TJ > TSD(shutdown) |
The device turns on when VIN is greater than VUVLO(RISING) and VADJ/EN is greater than the enable rising threshold VIH.
