6.1 Absolute Maximum Ratings

at TA = –40°C to +125°C (unless otherwise noted); all voltages are with respect to GND(1)
MIN MAX UNIT
VIN Input voltage –0.3 6 V
VEN Enable voltage –0.3 VIN + 0.3 V
VOUT Output voltage –0.3 6 V
IOUT Maximum output current Internally limited
Output short-circuit duration Indefinite
TA Operating ambient temperature –40 150 °C
TJ Operating junction temperature –40 150 °C
Tstg Storage temperature –55 150 °C
(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
