6.5 Electrical Characteristics
Over operating temperature range (T_J = –40°C to 125°C), V_IN = V_OUT(nom) + 0.5 V or 2.2 V, whichever is greater; I_OUT =
100 μA, V_VSET = V_EN = V_IN, C_OUT = 1.0 μF, fixed or adjustable, unless otherwise noted. Typical values at T_J = 25°C.

(1) The output voltage for V_SET = low/high is programmed at the factory.
(2) Adjustable version only.
(3) No V_SET pin on the adjustable version.
(4) No dynamic voltage scaling on the adjustable version.
(5) V_DO is not measured for devices with V_OUT(nom) < 2.3 V because minimum V_IN = 2.2 V.
(6) I_GND = 800 nA (max) up to 100°C.
(7) The TPS78001 FB pin is tied to V_OUT. Adjustable version only.
(8) Time from V_EN = 1.2 V to V_OUT = 90% (V_OUT(nom)).
(9) Time from V_EN = 0.4 V to V_OUT = 10% (V_OUT(nom)).
(10) See Shutdown for more details.
