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 MAX6033 family requires a minimum output capac-
itance of 0.1µF for stability and is stable with capacitive
loads (including the bypass capacitance) of up to
100µF. In applications 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.
The quiescent supply current of the MAX6033 series
reference is typically 40µA and is virtually independent
of the supply voltage. In the MAX6033 family, the load
current is drawn from the input only when required, so
supply current is not wasted and efficiency is maxi-
mized at all input voltages. This improved efficiency
reduces power dissipation and extends battery life.
When the supply voltage is below the minimum-speci-
fied input voltage (as during turn-on), the devices can
draw up to 150µA 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 in the output
voltage at T
cycled over its entire operating temperature range.
Hysteresis is caused by differential package stress
appearing across the bandgap core transistors. The
typical temperature hysteresis value is 150ppm.

FUNCTION
Supply Current
These devices typically turn on and settle to within
0.01% of their final value in >1µs. The turn-on time can
increase up to 2ms with the device operating at the
minimum dropout voltage and the maximum load.
Figure 1 shows a typical circuit providing a precision
current source. The OUTF output provides the bias cur-
rent for the bipolar transistor. OUTS senses the voltage
across the resistor and adjusts the current sourced by
OUTF accordingly.
Figure 2 shows a typical circuit providing both the
power supply and reference for a high-resolution DAC.
A MAX6033 with 2.5V output provides the reference
voltage for the DAC.
