High-Supply-Voltage, Precision Voltage Reference in SOT23
General DescriptionThe MAX6035 is a high-voltage, precision micropower
voltage reference. This three-terminal device is available
with output voltage options of 2.5V, 3.0V, and 5.0V. It is an
excellent upgrade for industry-standard devices such as
the REF02 and REF43. The MAX6035 offers 14x lower
power than the REF02 and 5x lower power than the
REF43, as well as a reduced package size from an 8-pin
SO to a 3-pin SOT23. The MAX6035 features a proprietary
temperature coefficient curvature-correction circuit and
laser-trimmed, thin-film resistors that result in a very low
temperature coefficient of 25ppm/°C (max) and an initial
accuracy of ±0.2% (max).
The MAX6035 typically draws only 73µA of supply cur-
rent and can source 10mA or sink 2mA of load current.
Unlike conventional shunt-mode (two-terminal) refer-
ences that waste supply current and require an external
resistor, this device offers a supply current that is virtu-
ally independent of the supply voltage and does not
require an external resistor. Additionally, this internally
compensated device does not require an external com-
pensation capacitor, but is also stable with capacitive
loads up to 5µF. Eliminating the external compensation
capacitor saves valuable board area in space-critical
applications. The supply independent, ultra-low supply
current makes this device ideal for battery-operated,
high-performance systems.
The MAX6035 is available in a 3-pin SOT23 package
and is specified for operation from -40°C to +125°C.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Note 3:Temperature Coefficient is measured by the “box” method, i.e., the maximum ∆VOUTis divided by the maximum ∆T.
Note 4:Line and load regulation are measured with pulses and do not include output voltage fluctuation due to die-temperature
changes.
Note 5:Thermal Hysteresis is defined as the change in the output voltage at TA= +25°C before and after cycling the device from
TMAXto TMIN.
Note 6:Guaranteed by design.
Note 7:Although the source current is guaranteed to be 10mA, exercise caution to ensure that the package’s absolute power dissi-
pation rating is not exceeded.
