6.1 Absolute Maximum Ratings

over operating junction temperature range (unless otherwise noted)⁽¹⁾

		MIN	MAX	UNIT
Voltage⁽²⁾	IN	–0.3	6	V
	EN	–0.3	6	V
	OUT	–0.3	6	V
Current (source)	OUT	Internally limited
Output short-circuit duration		Indefinite
Operating junction, T_J		–55	150	°C
Storage, T_stg		–55	150	°C

(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods my affect device reliability.

(2) All voltages are with respect to GND pin.

6.2 ESD Ratings

			VALUE	UNIT
