7 Specifications

7.1 Absolute Maximum Ratings

over operating free-air temperature range (unless otherwise noted) ⁽¹⁾

		MIN	MAX	UNIT
V_I	Input voltage range⁽²⁾	–0.3	13.5	V
	Voltage range at EN	–0.3	V_I + 0.3	V

	Continuous total power dissipation	See Thermal Information
T_J	Operating junction temperature range	–40	125	°C
T_stg	Storage temperature range	−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) All voltage values are with respect to network terminal ground.

7.2 ESD Ratings

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

(1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.

7.3 Recommended Operating Conditions

over operating free-air temperature range (unless otherwise noted)

		MIN	MAX	UNIT
V_I⁽¹⁾	Input voltage	2.7	10	V
V_O	Output voltage range	1.2	5.5	V
I_O⁽²⁾	Output current	0	1.0	A
T_J⁽²⁾	Operating junction temperature	–40	125	°C

(1) Maximum V_IN = V_OUT + V_DO or 2.7V, whichever is greater.

(2) Continuous current and operating junction temperature are limited by internal protection circuitry, but it is not recommended that the device operate under conditions beyond those specified in this table for extended periods of time.
