Voltage Reference 3 Volt

The MAX6010 is a precision, low-noise, low-dropout,micropower voltage reference in a SOT23 package. This three-terminal voltage reference operates with an input voltage from 3.2V to 5.5V, and outputs 3V. The MAX6010 voltage reference consumes less than 5µA (max) of supply current and can source up to 7mA and sink up to 1mA of load current when the input is 5V. Unlike conventional shunt-mode (two-terminal) ref-erences that waste supply current and require an exter-nal resistor, the MAX6010 offers a supply current that is virtually independent of supply voltage (with only 0.05µA/V variation with supply voltage) and does not require an external resistor. The MAX6010 has initial accuracies of 0.2% (A grade) and 0.4% (B grade) and a temperature drift of 50ppm/°C (max). The low-dropout voltage and the ultra-low supply current over the full voltage range make this device ideal for portable andbattery-operated applications. The MAX6010 is avail-able in a small, 3-pin SOT23 package.
