Detailed Description
The MAX6069 family consists of precision, two-
terminal, shunt bandgap voltage references. On-chip,
thin-film resistors are laser-trimmed to provide 0.2% output
voltage accuracies. Voltages of +1.25V, +2.048V, +2.5V,
and +3.0V are available in a space-saving 4-bump WLP.
Applications Information
Output/Load Capacitance
Bypass OUT to GND with a 0.01μF or larger capacitor.
In applications where the load or the supply can experience
step changes, additional capacitance will reduce the
amount of overshoot (or undershoot) and assist the
circuit’s transient response.
Output Voltage Hysteresis
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 200ppm.
Turn-On Time
The output capacitance and bias current of the MAX6069
greatly affect turn-on settling time. In the Typical Operating
Characteristics, turn-on time is shown with a 10nF out-
put capacitor and a 1.2μA bias current. Under these
conditions, the MAX6069 settles in about 4ms. Settling
time linearly decreases in proportion to the circuit’s bias
current.
