Detailed Description
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.
Shutdown
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.
MAX6037_ADJ Adjustable Output Voltage
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
ADJ
= 1.184V. Set R2 = 1M
or less. Currents
through Resistor R1 and R2 add to the quiescent supply
current.
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.
Thermal Hysteresis
Output voltage hysteresis is the change of output volt-
age at T
A
= +25°C before and after the device is
cycled over its entire operating temperature range. The
typical thermal hysteresis value is 500ppm.
