Ultra-Low-Power Precision Series Voltage Reference
MAX6029Ultra-Low-Power Precision Series
Voltage Reference
General DescriptionThe MAX6029 micropower, low-dropout bandgap volt-
age reference combines ultra-low supply current and
low drift in a miniature 5-pin SOT23 surface-mount pack-
age 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 stabili-
ty 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 avail-
able in a 5-pin SOT23 or an 8-pin SO package and is
specified over the extended temperature range (-40°C
to +85°C).

Note 1:MAX6029 is 100% production tested at TA= +25°C and is guaranteed by design for TA= TMINto TMAXas specified.
Note 2:Temperature coefficient is defined by box method: (VMAX- VMIN)/(ΔT ✕V+25°C).
Note 3:Not production tested. Guaranteed by design.
Note 4:Thermal hysteresis is defined as the change in TA= +25°C output voltage before and after temperature cycling of the
device (from TA= TMINto TMAX). Initial measurement at TA= +25°C is followed by temperature cycling the device to TA=
+85°C then to TA= -40°C and another measurement at TA= +25°C is compared to the original measurement at TA= +25°C.
Note 5:Dropout voltage is the minimum input voltage at which VOUTchanges by 0.1% from VOUTat rated VINand is guaranteed by
Load Regulation Test.
