Ultra-Low-Power Series Voltage Reference  
General Description  
Features  
The MAX6129 micropower, low-dropout bandgap volt-  
age reference combines ultra-low supply current and  
low drift in a miniature 5-pin SOT23 surface-mount  
package that uses 70% less board space than compa-  
rable devices in an SO package. This series-mode volt-  
age reference sources up to 4mA and sinks up to 1mA  
of load current. A wide 2.5V to 12.6V supply range,  
ultra-low 5.25µA (max) supply current, and a low  
200mV dropout voltage make these devices ideal for  
battery-operated systems.  
o Ultra-Low 5.25µA (max) Supply Current  
o 4mA Output Source Current  
o 1mA Output Sink Current  
o ±±.4ꢀ (max) ꢁnitial Accuracy  
o 4±ppm/°C (max) Temperature Coefficient  
o 2.5V to 12.6V Supply Range  
o Low 2±±mV Dropout  
An initial accuracy of 0.4% and a 40ppm/°C (max) tem-  
perature coefficient make the MAX6129 suitable for  
precision applications. Additionally, an internal com-  
pensation capacitor eliminates the need for an external  
compensation capacitor and ensures stability with load  
capacitances up to 10µF.  
o Stable with Capacitive Loads Up to 1±µF  
o No External Capacitors Required  
o Miniature 5-Pin SOT23 Package  
The MAX6129 provides six output voltages of 2.048V,  
2.5V, 3V, 3.3V, 4.096V, and 5V. The MAX6129 is avail-  
able in a 5-pin SOT23 package and is specified over  
the extended temperature range (-40°C to +85°C).
