The is a high-voltage, precision micropower voltage reference. This three-terminal device is available with output voltage options 2.5V, 3.0V, and 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 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 current and can source 10mA or sink 2mA of load current. Unlike conventional shunt-mode (two-terminal) references that waste supply current and require an external resistor, this device offers a supply current that is virtually independent of the supply voltage and does not require an external resistor. Additionally, this internally compensated device does not require an external compensation capacitor, but is also stable with capacitive loads 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 3-pin SOT23 package and is specified for operation from to +125°C.Features
