The MAX6037 is a family of low-dropout, micropower
voltage references. These devices all feature a shut-
down mode by forcing SHDN low, dropping the quies-
cent current to less than 500nA. The MAX6037 can sink
and source up to 5mA with less than 410mV of dropout
voltage, making them attractive for use in low-voltage
applications. The MAX6037 is available in six fixed out-
put voltages of 1.25V, 2.048V, 2.5V, 3.0V, 3.3V and
4.096V, and an adjustable output version for voltages
between the range of 1.184V and 5V.
The MAX6037 features an active-low shutdown mode.
Pulling SHDN low disables the output and forces the
quiescent current to less than 500nA (typically 50pA).
Connect SHDN to IN for normal operation.

Set the output voltage on the MAX6037_ADJ by placing
a resistor-divider network between OUT, ADJ, and GND
(See Figure 1). Use the following formula to calculate
the output voltage:
where V
through Resistor R1 and R2 add to the quiescent supply
current.
The quiescent supply current of the series-mode
MAX6037 family is typically 190µA to 210µA. When the
supply voltage is below the minimum-specified input
voltage during turn-on, the device can draw up to
250µA beyond the nominal supply current. The input
voltage source must be capable of providing this cur-
rent to ensure reliable turn-on.
Output voltage hysteresis is the change of output volt-
age at T
cycled over its entire operating temperature range. The
typical thermal hysteresis value is 500ppm.
