6.5 Electrical Characteristics

at ambient temperature (TA) = –40°C to +85°C, VIN = VOUT(typ) + 1 V or 2.7 V (whichever is greater), IOUT = 1 mA, VEN = 2 V,

and CIN = COUT = 2.2-μF ceramic (unless otherwise noted); typical values are at TA = 25°C

(1)

VDO is measured with VIN = 0.98 × VOUT(nom).

(2)

Start-up time = time from EN assertion to 0.95 × VOUT(nom) and load = 47 Ω.

(3)

Dropout is only valid when VOUT ≥ 2.8 V because of the minimum input voltage limits.

(4)

Measured with VIN = VOUT + 3 V for VOUT ≤ 2.5 V. Measured with VIN = VOUT + 2.5 V for VOUT > 2.5 V.
