(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 VIN + 0.3 V or 7 V, whichever is smaller.

(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.
6.5 Electrical Characteristics
Over the full operating temperature range (see Recommended Operating Conditions), VEN = 1.1 V, VFB = VOUT(1), 1.425 V ≤ VIN ≤ 6.5 V, 10 µA ≤ IOUT ≤ 3 A, COUT = 10 μF (unless otherwise noted). Typical values are at TJ = 25°C.

(1) When setting V
OUT to a value other than 0.5 V, connect R
2 to the FB pin using 27-kΩ ≤ R
2 ≤ 33-kΩ resistors. See
Figure 7 for details of R
1 and R
2.
(2) Accuracy does not include error on feedback resistors R1 and R2.
(3) TPS7A7002 is not tested at VOUT = 0.5 V, 2.3 V ≤ VIN ≤ 6.5 V, and 500 mA ≤ IOUT ≤ 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) VIN = VOUT + 0.5 V or 1.425 V, whichever is greater.
(5) VDO = VIN – VOUT with VFB = GND configuration.
