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 IN as possible. Where transient performance is less
important, no capacitor is necessary.
Devices in the MAX6100 family do not require an output
capacitance for frequency stability. They are stable for
any capacitive load when sourcing less than 200µA.
When sourcing greater than 200µA, the output may
become unstable with capacitive loads between 0.5nF
and 50nF. In applications where the load or the supply
can experience step changes, an output capacitor
reduces the amount of overshoot (undershoot) and
improves the circuit’s transient response. Many applica-
tions do not require an external capacitor, and the
MAX6100 family can offer a significant advantage in
these applications when board space is critical.

The quiescent supply current of the series-mode
MAX6100 family is typically 90µA and is virtually indepen-
dent of the supply voltage, with only an 8µA/V (max) vari-
ation with supply voltage. Unlike series references,
shunt-mode references operate with a series resistor con-
nected to the power supply. The quiescent current of a
shunt-mode reference is thus a function of the input volt-
age. Additionally, shunt-mode references have to be
biased at the maximum-expected load current, even if the
load current is not present at the time. In the MAX6100
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 dissipation and
extends battery life. When the supply voltage is below the
minimum specified input voltage (as during turn-on), the
devices can draw up to 400µA beyond the nominal
supply current. The input voltage source must be capable
of providing this current to ensure reliable turn-on.
Output voltage hysteresis is the change of 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 tem-
perature hysteresis value is 130ppm.
