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 -40C
to +85C.
The MAX6034 family of series-mode voltage references
typically draw only 90A of supply current and can
source 1mA and sink 200A 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 (16A/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 1F 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.
