7.1 Absolute Maximum Ratings

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

		MIN	MAX	UNIT
V_I	Voltage at VIN⁽²⁾	–0.3	6	V
	Voltage at VOUT⁽²⁾	–0.3	3.6
	Voltage at EN, MODE⁽²⁾	–0.3	V_IN + 0.3
	Peak output current		1600	mA
T_J	Operating internal junction temperature range	–40	125	°C
T_stg	Storage temperature range	–55	125	°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 ground terminal.

7.2 ESD Ratings

			VALUE	UNIT
V_(ESD)	Electrostatic discharge ⁽¹⁾⁽²⁾	Human body model	±2000	V
		Charge device model	±500	V
		Machine model	±100	V

(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.

7.3 Recommended Operating Conditions

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

			MIN	MAX	UNIT
VIN	Input voltage range		2.5	5.5	V
I_OUT	Peak output current for TPS8268090, TPS8268105, TPS8268120	VIN ≥ 2.8V	0	1600⁽¹⁾	mA
I_OUT	Peak output current for TPS8268150, TPS8268180	VIN ≥ 3.2V	0	1600⁽¹⁾	mA
I_OUT	Average output current for TPS8268090, TPS8268105, TPS8268120	VIN ≥ 2.7V	0	1200⁽¹⁾	mA
I_OUT	Average output current for TPS8268150, TPS8268180	VIN ≥ 2.9V	0	1200⁽¹⁾	mA
I_OUT	Average output current during soft-start	Vout ≤ 0.9 x V_OUT,nom	0	1000⁽²⁾	mA
	Additional effective input capacitance		0		µF
	Additional effective output capacitance		0	30⁽³⁾	µF
T_A	Operating ambient temperature range		–40	85	°C

(1) See Thermal and Reliability Information for additional details

(2) See Soft Start for additional details

(3) Due to the dc bias effect of ceramic capacitors, the effective capacitance is lower then the nominal value when a voltage is applied.
