General Description
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.
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.
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).
