● Stable with C
The MAX6012/MAX6021/MAX6025/MAX6030/MAX6041/
MAX6045/MAX6050 precision, low-dropout, micropower
voltage references are available in miniature SOT23-3
surface-mount packages. They feature a proprietary
curvature-correction circuit and laser-trimmed thin-film
resistors that result in a low temperature coefficient of
<15ppm/°C and initial accuracy of better than 0.2%.
These devices are specified over the extended tempera-
ture range.

LOAD
These series-mode voltage references draw only 27μA
of quiescent supply current and can sink or source up to
500μA of load current. Unlike conventional shunt-mode
(two-terminal) references that waste supply current and
require an external resistor, devices in the MAX6012
family offer a supply current that’s virtually independent
of supply voltage (with only a 0.8μA/V variation with
supply voltage) and do not require an external resistor.
Additionally, these internally compensated devices do
not require an external compensation capacitor and are
stable with up to 2.2nF of load capacitance. Eliminating
the external compensation capacitor saves valuable
board area in space-critical applications. Their low drop-
out voltage and supply-independent, ultra-low supply
current make these devices ideal for battery-operated,
low-voltage systems.
