General Description

The MAX6034 family of precision, low-dropout, microp-

ower voltage references are available in the miniature

3-pin SC70 surface-mount package. They feature a

proprietary temperature coefficient curvature-correction

circuit and laser-trimmed, thin-film resistors that result

in a low temperature coefficient of 30ppm/°C (max) and

initial accuracy of ±0.20% (max). These devices are

available over the extended temperature range of -40°C

to +85°C.

The MAX6034 family of series-mode voltage references

typically draw only 90µA of supply current and can

source 1mA and sink 200µA of load current. Unlike

conventional shunt-mode (two terminal) references that

waste supply current and require an external resistor,

devices in the MAX6034 family offer supply current that

is virtually independent of supply voltage (16µA/V, max

variation) and do not require an external resistor. These

internally compensated devices do not require an

external compensation capacitor, but are stable with up

to 1µF of load capacitance. Eliminating the external

compensation capacitor saves valuable board space in

space-critical applications. The low dropout voltage

and supply-independent, ultra-low supply current make

the MAX6034 ideal for battery-powered applications.
