Disabled

The device is disabled under the following conditions:

  • |VEN| > high-level enable pin input voltage (2 V)
  • The device junction temperature is greater than the thermal shutdown temperature

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

Table 1. Device Functional Mode Comparison

OPERATING MODE PARAMETER
VIN VEN IOUT TJ
Normal mode |VIN| > \{ |VOUT(nom)| + |VDO|, |VIN(min)| \} |VEN| < 0.7 V I OUT< ICL T J< 125°C
Dropout mode |VIN(min)| < |VIN| < |VOUT(nom)| + |VDO| |VEN| < 0.7 V TJ< 125°C
Disabled mode
(any true condition disables the device)
|VEN| > 2 V TJ> 170°C
