Applications Information
Bypassing/Load Capacitance
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 MAX6133
family requires a minimum output capacitance of 0.1μF
for stability and is stable with capacitive loads (includ-
ing the bypass capacitance) of up to 100μF. In applica-
tions where the load or the supply can experience 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.
Supply Current
The quiescent supply current of the MAX6133 series
reference is typically 40μA and is virtually independent
of the supply voltage. In the MAX6133 family, the load
current is drawn from the input only when required, so
supply current is not wasted and efficiency is maxi-
Turn-On Time
These devices typically turn on and settle to within
0.01% of their final value in <1ms. The turn-on time can
increase up to 2ms with the device operating at the
minimum dropout voltage and the maximum load.
Low-Power, 14-Bit DAC
with MAX6133 as a Reference
Figure 1 shows a typical application circuit for the
MAX6133 providing both the power supply and precision
reference voltage for a 14-bit high-resolution, serial-
input, voltage-output digital-to-analog converter. The
MAX6133 with a 2.5V output provides the reference volt-
age for the DAC.

mized at all input voltages. This improved efficiency
reduces power dissipation and extends battery life.

fied input voltage (as during turn-on), the devices can

draw up to 150μA beyond the nominal supply current.
OUTPUT
The input voltage source must be capable of providing
this current to ensure reliable turn-on.
Thermal Hysteresis
Thermal hysteresis is the change in the 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 ther-
mal hysteresis value is 120ppm for both SO and μMAX
packages.
