SBVS330A – SEPTEMBER 2017 – REVISED OCTOBER 2017
6.5 Electrical Characteristics
at TJ = –55°C to +125°C, VIN = VOUT(nom) + 0.3 V or 2.7 V, whichever is greater; IOUT = 1 mA, VEN = VIN, COUT = 2.2 μF, CNR =
0.01 μF, and VOUT = 3 V (unless otherwise noted). Typical values are at TJ = 25°C.

(1) Minimum VIN = VOUT + VDO or 2.7 V, whichever is greater.
(2) VDO is not measured for VOUT(nom) < 2.8 V because minimum VIN = 2.7 V.
