Note 1: All devices are 100% tested at T
A
= +25°C and are guaranteed by design for T
A
= T
MIN
to T
MAX
, as specified.
Note 2: Temperature coefficient is measured by the “box” method, i.e., the maximum ∆V
OUT
/ V
OUT
is divided by the maximum ∆T.
Note 3: Thermal hysteresis is defined as the change in +25°C output voltage before and after cycling the device from T
MAX
to
T
MIN
.
Note 4: Not production tested. Guaranteed by design.
Note 5: Dropout voltage is defined as the minimum differential voltage (V
IN
- V
OUT
) at which V
OUT
decreases by 1% from its origi-
nal value at V
IN
= +5.0V.
Note 6: V
OUT
initial accuracy for the MAX6037_ADJ is tested with ADJ shorted to OUT. Actual accuracy will be affected by match-
ing and the temperature coefficient of the external resistors used. Use 1% resistors with low temperature coefficient for
best overall accuracy.
Note 7: The temperature coefficient for the MAX6037_ADJ is specified for the case where ADJ is connected to OUT. For the case
where an external resistive network is used to set the output voltage, actual change in reference output over temperature
will be affected by the temperature coefficient and matching of the external resistors used.
Note 8: The minimum V
IN
is the greater of +2.5V and (V
OUT
+ 0.2V).
Note 9: V
OUT
set to +5V with an external resistive-divider.
Note 10: Noise for the MAX6037_ADJ is specified for a +1.25V output. Noise is proportional to V
OUT
and is greater for higher output
voltages. In addition, external resistors used to set the output voltage can contribute to noise.
