6.5 Electrical Characteristics
At TJ = â40°C to 105°C, VIN = VOUT(nom) + 0.5 V or 2.2 V, whichever is greater; IOUT = 100 μA, VEN = VIN, COUT = 1.0 μF,
and fixed VOUT test conditions (unless otherwise noted). Typical values at TJ = 25°C.

(1) VDO is not measured for devices with VOUT(nom) ⤠2.3 V because minimum VIN = 2.2 V.
(2) VIN(min) = (VOUT(nom) + 0.5 V) or 2.2 V, whichever is greater.
(3) See Shutdown in the Application and Implementation section for more details.
(4) Time from VEN = 1.2 V to VOUT = 90% (VOUT(nom)).
