Note 1:
MAX6129 is 100% production tested at T
A
= +25
°
C and is guaranteed by design for T
A
= T
MIN
to T
MAX
as specified.
Note 2:
Temperature coefficient is defined by box method: (V
MAX
- V
MIN
)/(
T
V

C
).
Note 3:
Not production tested. Guaranteed by design.
Note 4:
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 5:
Dropout voltage is the minimum input voltage at which V
OUT
changes by 0.1% from V
OUT
at rated V
IN
and is guaranteed by
Load Regulation Test.
