For the best line-transient performance, decouple the
input with a 0.1µF ceramic capacitor as shown in the
Typical Operating Circuit. Place the capacitor as close
to IN as possible. When transient performance is less
important, no capacitor is necessary.
The MAX6043 does not require an output capacitor for
stability and is stable with capacitive loads up to 100µF.
In applications where the load or the supply can experi-
ence step changes, a larger output capacitor reduces
the amount of overshoot (undershoot) and improves the
circuit’s transient response. Place output capacitors as
close to the device as possible for best performance.
The MAX6043 consumes 320µA of quiescent supply
current. This improved efficiency reduces power dissi-
pation and extends battery life.
Thermal hysteresis is the change in the output voltage
at T
over its entire operating temperature range. Hysteresis
is caused by differential package stress appearing
across the bandgap core transistors. The typical ther-
mal hysteresis value is 150ppm.

The MAX6043 typically turns on and settles to within
0.05% of the preset output voltage in 150µs.
The MAX6043 features a short-circuit-protected output.
Internal circuitry limits the output current to 60mA when
short-circuiting the output.
In a data converter application, the reference voltage of
the converter must stay within a certain limit to keep the
error in the data converter smaller than the resolution
limit through the operating temperature range. Figure 1
shows the maximum allowable reference-voltage tem-
perature coefficient to keep the conversion error to less
than 1 LSB, as a function of the operating temperature
range (T
parameter. The graph assumes the reference-voltage
temperature coefficient as the only parameter affecting
accuracy.
In reality, the absolute static accuracy of a data convert-
er is dependent on the combination of many parameters
such as integral nonlinearity, differential nonlinearity,
offset error, gain error, as well as voltage-reference
changes.
