Output Voltage. Bias OUT with a pullup resistor to a potential greater than OUT. Bypass
OUT to GND with a 0.01 μ F or larger capacitor.

Internally connected test point. Leave this pin unconnected, or connect to GND.
No connection. Not internally connected.
Detailed Description
The MAX6006–MAX6009 are precision, two-terminal,
series bandgap voltage references. On-chip thin-film
resistors are laser trimmed to provide 0.2% output volt-
age accuracies. Voltages of +1.25V, +2.048V, +2.5V,
and +3.0V are available in the space-saving SOT23
package (2.1mm   2.7mm).
Applications Information
Output/Load Capacitance
For devices in this family, OUT needs to be bypassed
to GND with a 0.01μF or larger capacitor. In applica-
tions where the load or the supply can experience step
changes, additional capacitance will reduce the
amount of overshoot (or undershoot) and assist the cir-
cuit’s transient response.
Output Voltage Hysteresis
Typical Applications
In the typical shunt regulator application shown in
Figure 1, R BIAS is used to set the current through the
load (I L ) and the current through the shunt regulator
(I RMIN ). There are two worst-case situations that R BIAS
needs to be sized for:
1) R BIAS must be small enough that when V S (supply
voltage) is at its minimum and I L is at its maximum,
I RMIN is equal to at least the minimum operating
current of the shunt regulator.
2) R BIAS must be large enough that when V S is at its
maximum and I L is at its minimum, I RMIN is < 2mA.
V S
Output voltage 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
temperature hysteresis value is typically less than

Turn-On Time
The output capacitance and bias current of the
MAX6006 –MAX6009 greatly affects turn-on settling
time. In the Typical Operating Characteristics, turn-on
time is shown with a 10nF output capacitor and a 1.2μA
bias current. Under these conditions, the MAX6006–
MAX6009 settle in 40ms. Settling time will linearly
decrease in proportion to the circuit’s bias current.
