6.6 Electrical Characteristics: TPS7A8400A

Over operating junction temperature range (T_J = –40°C to +125°C), V_IN = 1.4 V or V_IN = V_OUT(nom) + 0.4 V (whichever is greater), V_BIAS = open, V_OUT(nom) = 0.8 V⁽¹⁾, OUT connected to 50 Ω to GND⁽²⁾, V_EN = 1.1 V, C_IN = 10 μF, C_OUT = 47 μF, C_NR/SS =0nF, without C_FF, and PG pin pulled up to V_IN with 100 kΩ, unless otherwise noted. Typical values are at T_J = 25°C.

(1) V_OUT(nom) is the calculated V_OUT target value from the ANY-OUT in a fixed configuration. In an adjustable configuration, V_OUT(nom) is the expected V_OUT value set by the external feedback resistors.

(2) This 50-Ω load is disconnected when the test conditions specify an I_OUT value.

(3) When the device is connected to external feedback resistors at the FB pin, external resistor tolerances are not included.

(4) The device is not tested under conditions where V_IN > V_OUT + 1.7 V and I_OUT = 3 A, because the power dissipation is higher than the maximum rating of the package.

(5) For V_OUT ≤ 5 V, V_IN = V_OUT + 0.4 V; For V_OUT > 5 V, V_IN = V_OUT + 0.45 V
