MAX6029EUK30T Datasheet, PDF (1/16 Pages) Maxim Integrated Products – Ultra-Low-Power Precision Series Voltage Reference

19-2892; Rev 2; 11/06
Ultra-Low-Power Precision Series
Voltage Reference
General Description
The 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).
