MAX6006–MAX6009
1µA SOT23 Precision Shunt
Voltage Reference
General Description
Features
o Ultra-Low Operating Current: Guaranteed < 1µA
The MAX6006–MAX6009 ultra-low-power shunt refer-
ences are ideal for space-critical and low-power appli-
cations. They are offered in 3-pin SOT23 packages, and
the minimum operating current is guaranteed to be
< 1µA. The devices feature low temperature coefficients
of <30ppm/°C and initial accuracy of better than 0.2%.
o Small 3-Pin SOT23 Package
o Initial Voltage Accuracy: 0.2%
o Temperature Coefficient: 30ppm/°C max
o Temperature Range: -40°C to +85°C
Available in +1.25V, +2.048V, +2.5V, and 3V output volt-
ages, the MAX6006–MAX6009 have references of
+1.25V, +2.048V, +2.5V, and +3.0V, respectively. The
devices can be used as lower-power, higher-precision
upgrades to the ICL8069, LM385, LT1004, and LM4040
references. The MAX6006–MAX6009 are available in
two grades: A and B. The A grade features a tempera-
ture coefficient of 30ppm/°C over the extended temper-
ature range of -40°C to +85°C, with an initial accuracy of
0.2%. Grade B features a temperature coefficient of
75ppm/°C with an initial accuracy of 0.5%. MAX6006 in
+1.25V and MAX6008 in +2.5V are offered in 8-pin SO
packages, as plug in upgrades for LT1004 and LM285.
o Factory-Trimmed Output Voltages: +1.25V,
+2.048V, +2.5V, +3.0V
o Wide Operating Range: 1µA to 2mA

Detailed Description
Typical Applications
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
In the typical shunt regulator application shown in
Figure 1, R
is used to set the current through the
BIAS
load (I ) and the current through the shunt regulator
L
(I
RMIN
). There are two worst-case situations that R
BIAS
needs to be sized for:
ꢀ
package (2.1mm 2.7mm).
1) R must be small enough that when V (supply
BIAS
S
voltage) is at its minimum and I is at its maximum,
L
Applications Information
I
is equal to at least the minimum operating
RMIN
current of the shunt regulator.
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.
2) R must be large enough that when V is at its
BIAS
S
maximum and I is at its minimum, I
is < 2mA.

Output Voltage Hysteresis
Output voltage hysteresis is the change in the output

+ I
L
RMIN

BIAS
voltage at T = +25°C before and after the device is
A
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
200ppm.

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.
