8.1 Absolute Maximum Ratings

MIN MAX UNIT
VIN Input voltage range –0.3 6 V
VOUT Output voltage range –0.3 6 V
VON Input voltage range –0.3 6 V
IMAX Maximum continuous switch current 2 A
IPLS Maximum pulsed switch current, pulse < 300 µs, 2% duty cycle 2.5 A

8.2 ESD Ratings

VALUE UNIT
V(ESD) Electrostatic discharge Human-body model (HBM), per ANSI/ESDA/JEDEC JS-001(1) ±2000 V
Charged-device model (CDM), per JEDEC specification JESD22-C101(2) ±1000
(1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process. Manufacturing with less than 500-V HBM is possible with the necessary precautions. Pins listed as ±2000 V may actually have higher performance.
(2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process. Manufacturing with less than 250-V CDM is possible with the necessary precautions. Pins listed as ±1000 V may actually have higher performance.
