rent, even if the load current is not present at the time.
In the MAX6035 family, the load current is drawn from
the input voltage only when required, so supply current
is not wasted and efficiency is maximized at all input
voltages. This improved efficiency reduces power dissi-
pation and extends battery life.
Thermal Hysteresis
Thermal hysteresis is the change of output voltage at
T A = +25 ° C before and after the device is cycled over
Applications Information
Input Bypassing
For the best line-transient performance, decouple the
input with a 0.1μF ceramic capacitor as shown in the
Typical Operating Circuit . Locate the capacitor as
close to the device as possible. Where transient perfor-
mance is less important, no capacitor is necessary.
Output/Load Capacitance
Devices in the MAX6035 family do not require any out-
put capacitance for frequency stability. In applications
where the load or the supply can experience step
changes, an output capacitor of at least 0.1μF reduces
the amount of overshoot (undershoot) and improves the
circuit ’ s transient response. Many applications do not
require an external capacitor, and the MAX6035 family
can offer a significant advantage in these applications
when board space is critical.
Supply Current
The quiescent supply current of the MAX6035 series-
mode family is typically 73μA and is virtually indepen-
dent of the supply voltage, with only a 0.7μA/V (max)
variation with supply voltage. In contrast, the quiescent
current of a shunt-mode reference is a function of the
input voltage due to a series resistor connected to the
its entire operating temperature range. The typical tem-
perature hysteresis value is 135ppm.
Turn-On Time
These devices typically turn on and settle to within
0.1% of their final value in 240μs. Increased output
capacitance also increases turn-on time.
Temperature Coefficient vs.
Operating Temperature Range
for a 1 LSB 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 3
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.
In reality, the absolute static accuracy of a data con-
verter is dependent on the combination of many para-
meters such as integral nonlinearity, differential
nonlinearity, offset error, gain error, as well as voltage
reference changes
