19-4601; Rev 0; 4/09 Precision, Micropower, 3V Series Voltage Reference in SOT23 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) references that waste supply current and require an external 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 and battery-operated applications. The MAX6010 is available in a small, 3-pin SOT23 package.

This three-terminal reference operates with an input voltage from 3.2V to 5.5V, and outputs 3V. The device sources up to 7mA with < 200mV of dropout voltage and requires only 5µA (max) supply current. Applications Information Output/Load Capacitance The MAX6010 requires a minimum of 1nF load to maintain output stability. The device remains stable for capacitive loads as high as 1µF. In applications where the load or the supply can experience step changes, a larger output capacitor reduces the amount of overshoot (or undershoot) and assists the circuit’s transient response. Pin Description PIN NAME 1 IN FUNCTION 2 OUT Reference Voltage Output. Bypass with at least 1nF to ground. (See the Output/Load Capacitance section.) 3 GND Ground Supply Voltage Input The input voltage source must be capable of providing this current to ensure reliable turn-on. Turn-On Time The MAX6010 typically turns on and settles to within 0.1% of the final value in 700µs. The turn-on time can increase with the device operating at the minimum dropout voltage and the maximum load. Supply Current The 5µA maximum supply current varies only 0.05µA/V with the supply voltage. When the supply voltage is below the minimum-specified input voltage (as during turn-on), the device can draw up to 20µA beyond the nominal supply current. _______________________________________________________________________________________ 5 MAX6010 Typical Operating Characteristics (continued) (VIN = 5V, CIN = 0.1µF, COUT = 0.1µF.
