6.4.3 Disabled

The device is disabled under the following conditions:

  • The input or bias voltages are below the respective minimum specifications.
  • The enable voltage is less than the enable falling threshold voltage or has not yet exceeded the enable rising threshold.
  • The device junction temperature is greater than the thermal shutdown temperature.

Table 6-1 shows the conditions that lead to the different modes of operation.

Table 6-1 Device Functional Mode Comparison
OPERATING MODE PARAMETER
VIN VEN VBIAS IOUT TJ
Normal mode VIN > VOUT(nom) + VDO (VIN) VEN > VEN, HI VBIAS ≥ VOUT + 1.39 V IOUT < ICL TJ < 125°C
Dropout mode VIN < VOUT(nom) + VDO (VIN) VEN > VEN, HI VBIAS < VOUT + 1.39 V — TJ < 125°C
Disabled mode (any true condition the device) VIN < VIN(min) VEN < VEN, LO VBIAS < VBIAS(min) — TJ > 165°C
