1µA SOT23 Precision Shunt
Voltage Reference
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
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 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
temperature hysteresis value is typically less than
200ppm.
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.
