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 IN as possible. Where transient performance is
less important, no capacitor is necessary.
Output/Load Capacitance
Devices in the MAX6101 family do not require an output
capacitance for frequency stability. They are stable for
capacitive loads from 0 to 1μF. However, in applications
where the load or the supply can experience step
changes, an output capacitor will reduce the amount of
overshoot (undershoot) and improve the circuit’s
transient response. Many applications do not require an
external capacitor, and the MAX6101 family can offer a
significant advantage in these applications when board
space is critical.
Supply Current
The quiescent supply current of the series-mode
MAX6101 family is typically 90μA and is virtually indepen-
dent of the supply voltage, with only a 10μA/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 MAX6101
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
Output voltage hysteresis is the change of output voltage
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 bandgap core transistors. The typical tem-
perature hysteresis value is 130ppm.
