6.1 Absolute Maximum Ratings

Over operating free-air temperature range (unless otherwise noted) (1)
MIN MAX UNIT
VDD Supply voltage –0.3 6 V
PD Power dissipation Internally limited
Voltage EN –0.3 6 V
Voltage C2–, C1– –0.3 VIN or 5.5(2) V
Voltage C2+, C1+ –0.3 VIN, VOUT, or 5.5(2) V
TJ Junction temperature 125 °C
Short circuit output current 80 mA
Tstg Storage temperature –65 150 °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.
(2) Whichever is lowest.

6.2 ESD Ratings

VALUE UNIT
V(ESD) Electrostatic discharge Human body model (HBM), per ANSI/ESDA/JEDEC JS-001(1) ±2000 V
