ELECTRICAL CHARACTERISTICS (continued)
(Circuit of Figure 1: V
IN
= +1.8V, V
OUT
= +1.5V, EN = IN, I
OUT
= 2mA, T
A
= -40°C to +85°C, unless otherwise noted.) (Note 1)
Note 1: Specifications to T
A
= -40°C are guaranteed by design, not production tested.
Note 2: Measurements at high current are pulse tested, such that the junction temperature is ambient temperature. Minimum supply
voltage for output accuracy must be at least 1.425V.
