Description
The MAX6029 micropower, low-dropout bandgap voltage 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 comparable devices in an SO package. An initial accuracy of 0.15% and a 30ppm/°C (max) temperature coefficient make the MAX6029 suitable for precision applications. This series-mode voltage 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. Additionally, an internal compensation capacitor eliminates the need for an external compensation capacitor and ensures stability with load capacitances up to 10µF.

The MAX6029 provides six output voltages of 2.048V, 2.5V, 3V, 3.3V, 4.096V, and 5V. The MAX6029 is available in a 5-pin SOT23 or an 8-pin SO package and is specified over the extended temperature range (-40°C to +85°C).
