TPS780 Series
SBVS083D – JANUARY 2007 – REVISED SEPTEMBER 2012
ELECTRICAL CHARACTERISTICS
Over operating temperature range (T J = –40°C to +125°C), V IN = V OUT(NOM) + 0.5V or 2.2V, whichever is greater; I OUT =
100 μ A, V VSET = V EN = V IN , C OUT = 1.0 μ F, fixed or adjustable, unless otherwise noted. Typical values at T J = +25°C.

The output voltage for V SET = low/high is programmed at the factory.
Adjustable version only.
No V SET pin on the adjustable version.
No dynamic voltage scaling on the adjustable version.
V DO is not measured for devices with V OUT(NOM) < 2.3V because minimum V IN = 2.2V.
I GND = 800nA (max) up to +100°C.
The TPS78001 FB pin is tied to V OUT . Adjustable version only.
Time from V EN = 1.2V to V OUT = 90% (V OUT(NOM) ).
Time from V EN = 0.4V to V OUT = 10% (V OUT(NOM) ).
See Shutdown in the Application Information section for more details.
