Precision, Low-Power, Low-Dropout,
SOT23-3 Voltage References
General Description
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 temper-
ature range.
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 cur-
rent 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 vari-
ation 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 capac-
itance. Eliminating the external compensation capacitor
saves valuable board area in space-critical applications.
Their low dropout voltage and supply-independent,
ultra-low supply current make these devices ideal for
battery-operated, low-voltage systems.

Note 6: Many of the Typical Operating Characteristics of the MAX6012 family are
extremely similar. The extremes of these characteristics are found in the
MAX6012 (1.2V output) and the MAX6050 (5.0V output). The Typical
Operating Characteristics of the remainder of the MAX6012 family typically
lie between these two extremes and can be estimated based on their output
voltage.
