Precision, Micropower, 1.8V Supply, Low-Dropout, SOT23 Voltage Reference
The is a precision, low-voltage, low-dropout, micropower voltage reference a SOT23 package. This three-terminal reference operates with an input voltage from (VOUT to 5.5V, and is available with output voltage options 1.6V, 1.8V, and 2.048V The MAX6018 voltage reference consumes less than 5µA (max) of supply current and can source and sink 1mA of load current. Unlike conventional shuntmode (two-terminal) references that waste supply current and require an external resistor, devices in the MAX6018 family offer a supply current that is virtually independent of supply voltage (with only 0.1µA/V variation with supply voltage) and do not require an external resistor. The MAX6018 has initial accuracies 0.2% (A grade) and 0.4% (B grade) and temperature drift of 50ppm/°C (max). The low-dropout voltage and the ultra-low, supply voltage-independent supply current make this device ideal for two-cell alkaline, end-of-life, battery-monitoring systems. The MAX6018 is available in a tiny 3-pin SOT23 package. o 1.6V Output from 1.8V Input o Ultra-Small, 3-Pin SOT23 Package o Initial Accuracy: ±0.2% (max) o Low Temperature Drift: 50ppm/°C (max) o 200mV Dropout Voltage o Load Regulation (1mA Source): 700µV/mA (max) o Line Regulation (VOUT 5.5V: 250µV/V (max) o Four Output Voltage Options: 1.8V, 2.048VFeatures
