Note 1: 100% production tested at T
A
= +25°C. Guaranteed by design for T
A
= -40°C to +85°C.
Note 2: Temperature Coefficient is specified by the “box” method; i.e., the maximum ΔV
OUT
is divided by the maximum ΔT.
Note 3: Thermal Hysteresis is defined as the change in T
A
= +25°C output voltage before and after temperature cycling of the
device (from T
A
= T
MIN
to T
MAX
). Initial measurement at T
A
= +25°C is followed by temperature cycling the device to
T
A
= +85°C then to T
A
= -40°C, and another measurement at T
A
= +25°C is compared to the original measurement at
T
A
= +25°C.
Note 4: Dropout voltage is the minimum input voltage at which V
OUT
changes ≤ 0.2% from V
OUT
at V
IN
= 5.0V (V
IN
= 5.5V for
MAX6165).
