6 Specifications

6.1 Absolute Maximum Ratings

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

		MIN	MAX	UNIT
Voltage	IN	–0.3	7	V
Voltage	EN, FB, OUT	–0.3	V_IN + 0.3⁽²⁾	V
Current	OUT	Internally limited		A
Temperature	Operating virtual junction, T_J	–55	150	°C
Temperature	Storage temperature, 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, 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) The absolute maximum rating is V_IN + 0.3 V or 7 V, whichever is smaller.

6.2 ESD Ratings

			VALUE	UNIT
V_(ESD)	Electrostatic discharge	Human body model (HBM), per ANSI/ESDA/JEDEC JS-001⁽¹⁾	±2000	V
V_(ESD)	Electrostatic discharge	Charged-device model (CDM), per JEDEC specification JESD22-C101⁽²⁾	±500	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.

6.3 Recommended Operating Conditions

		MIN	NOM	MAX	UNIT
V_IN	Input voltage	1.425		6.5	V
V_EN	Enable pin voltage	0		V_IN	V
C_IN	Input capacitor	1		10	µF
C_OUT	Output capacitor⁽¹⁾⁽²⁾	4.7	10	200	µF
C_FB	Feedforward capacitance	0		100	nF
I_OUT	Output current	0		3	A
T_J	Junction temperature	–40		125	°C

(1) See Figure 1 and Figure 2 for additional output capacitor ESR requirements.

(2) For output capacitors larger than 47 µF, a feedforward capacitor of at least 220 pF must be used.

6.4 Thermal Information

THERMAL METRIC⁽¹⁾		TPS7A7002	UNIT

6.5 Electrical Characteristics

Over the full operating temperature range (see Recommended Operating Conditions), V_EN = 1.1 V, V_FB = V_OUT⁽¹⁾, 1.425 V ≤ V_IN ≤ 6.5 V, 10 µA ≤ I_OUT ≤ 3 A, C_OUT = 10 μF (unless otherwise noted). Typical values are at T_J = 25°C.

I_EN	EN pin current	V_EN = 0 V, V_IN = 3.3 V			0.2	µA
V_EN(LO)	EN pin input low (disable)	V_IN = 3.3 V	0		0.5	V
V_EN(HI)	EN pin input high (enable)	V_IN = 3.3 V	1.1		V_IN	V

(1) When setting V_OUT to a value other than 0.5 V, connect R₂ to the FB pin using 27-kΩ ≤ R₂ ≤ 33-kΩ resistors. See Figure 7 for details of R₁ and R₂.

(2) Accuracy does not include error on feedback resistors R₁ and R₂.

(3) TPS7A7002 is not tested at V_OUT = 0.5 V, 2.3 V ≤ V_IN ≤ 6.5 V, and 500 mA ≤ I_OUT ≤ 3 A because the power dissipation is higher than the maximum rating of the package. Also, this accuracy specification does not apply to any application condition that exceeds the power dissipation limit of the package.

(4) V_IN = V_OUT + 0.5 V or 1.425 V, whichever is greater.

(5) V_DO = V_IN – V_OUT with V_FB = GND configuration.
