7.1 Absolute Maximum Ratings⁽¹⁾

		MIN	MAX	UNIT
Voltage range⁽²⁾	VIN, PG, VOS	– 0.3	7	V
	SW	– 0.3	V_IN + 0.3	V
	SW (AC, less than 10 ns)⁽³⁾	– 3.0	10	V
	FB	– 0.3	3.6	V
	EN	– 0.3	V_IN+ 0.3	V
Power Good Sink Current	PG		1	mA
Operating junction temperature range, T_J		– 40	150	°C
Storage temperature range, T_stg		– 65	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 may affect device reliability.

(2) All voltage values are with respect to network ground terminal.

(3) While switching.

7.2 ESD Ratings

			VALUE	UNIT
V_(ESD)	Electrostatic discharge	Human body model (HBM) ESD stress voltage⁽¹⁾	±2000	V
V_(ESD)	Electrostatic discharge	Charged device model (CDM) ESD stress voltage⁽²⁾	±500	V

(1) Level listed above is the passing level per ANSI/ESDA/JEDEC JS-001. JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.

(2) Level listed above is the passing level per EIA-JEDEC JESD22-C101. JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process.

7.3 Recommended Operating Conditions⁽¹⁾

		MIN	MAX	UNIT
V_IN	Input voltage range, TLV62080	2.5	6	V
V_IN	Input voltage range, TLV62084, TLV62084A	2.7	6	V
T_J	Operating junction temperature	–40	125	°C
