PRODUCTION DATA
Table 6-1 shows the conditions that lead to the different modes of operation. See the Electrical Characteristics table for parameter values.
| OPERATING MODE | PARAMETER | ||||
|---|---|---|---|---|---|
| VIN | VBIAS | VEN | IOUT | TJ | |
| Normal mode | VIN ≥ VOUT(nom) + VDO(IN) and VIN ≥ VIN(min) | VBIAS ≥ VOUT + VDO(BIAS) | VEN ≥ VHI(EN) | IOUT < ICL | TJ < TSD for shutdown |
| Dropout mode | VIN(min) < VIN < VOUT(nom) + VDO(IN) | VBIAS < VOUT + VDO(BIAS) | VEN > VHI(EN) | IOUT < ICL | TJ < TSD for shutdown |
| Disabled mode (any true condition disables the device) |
VIN < VUVLO(IN) | VBIAS < VBIAS(UVLO) | VEN < VLO(EN) | — | TJ ≥ TSD for shutdown |
