= T
MIN
to T
MAX
, unless otherwise noted. Typical values are at T
A
= +25°C.)
Note 1: Temperature Coefficient is measured by the “box” method; i.e., the maximum ΔV
OUT
is divided by the maximum Δt.
Note 2: Thermal Hysteresis is defined as the change in +25°C output voltage before and after cycling the device from T
MIN
to T
MAX
.
Note 3: Not production tested. Guaranteed by design.
Note 4: Dropout voltage is the minimum input voltage at which V
OUT
changes ≤ 0.2% from V
OUT
at V
