(2) Adjustable version only. (3) No VSET pin on the adjustable version. (4) No dynamic voltage scaling on the adjustable version. (5) VDO is not measured for devices with VOUT(nom) < 2.3 V because minimum VIN = 2.2 V. (6) IGND = 800 nA (max) up to 100°C. (7) The TPS78001 FB pin is tied to VOUT. Adjustable version only. (8) Time from VEN = 1.2 V to VOUT = 90% (VOUT(nom)). (9) Time from VEN = 0.4 V to VOUT = 10% (VOUT(nom)). (10) See Shutdown for more details.
