6.1 Absolute Maximum Ratings

over operating free-air temperature range (unless otherwise noted) (1)
MIN MAX UNIT
VIN Input voltage –0.3 4 V
VOUT Output voltage VIN + 0.3 V
VON Control input voltage –0.3 4 V
IMAX Maximum continuous switch current, TA = –40°C to 85°C 1 A
IPLS Maximum pulsed switch current, 100-µs pulse, 2% duty cycle, TA = –40°C to 85°C 1.4 A
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.

6.2 ESD Ratings

VALUE UNIT
V(ESD) Electrostatic discharge Human body model (HBM), per ANSI/ESDA/JEDEC JS-001, all pins(1) ±3000 V
Charged device model (CDM), per JEDEC specification JESD22-C101, all pins(2) ±1000
(1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.
(2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process.
