General Description  
Features  
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.

8µV/V Line Regulation  
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.
