Reference Output
MAX6129 is very small, 5.25μA (max), and is very sta-
ble against changes in the supply voltage with only
1.5μA/V (max) variation with supply voltage. The
MAX6129 family draws load current from the input volt-
age source only when required, so supply current is not
wasted and efficiency is maximized at all input volt-
ages. This improved efficiency reduces power dissipa-
tion and extends battery life.
Applications Information
Input Bypassing
The MAX6129 does not require an input bypass capac-
itor. For improved transient performance, bypass the
input to ground with a 0.1μF ceramic capacitor. Place
the capacitor as close to IN as possible.
Load Capacitance
The MAX6129 does not require an output capacitor for
stability. The MAX6129 is stable driving capacitive
loads from 0 to 100pF and 0.1μF to 10μF when sourc-
ing current and from 0 to 0.4μF when sinking current. In
applications where the load or the supply can experi-
ence step changes, an output capacitor reduces the
amount of overshoot (undershoot) and improves the cir-
cuit ’s transient response. Many applications do not
require an external capacitor, and the MAX6129 offers
a significant advantage in applications where board
space is critical.
Output Thermal Hysteresis
Output thermal hysteresis is the change of output volt-
age at T A = +25°C before and after the device is
cycled over its entire operating temperature range.
Hysteresis is caused by differential package stress
appearing across the device.
Temperature Coefficient vs. Operating
Temperature Range for a 1LSB
Maximum Error
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 1LSB, as a function of the operating temperature
range (T MAX - T MIN ) with the converter resolution as a
parameter. The graph assumes the reference-voltage
temperature coefficient as the only parameter affecting
accuracy.
