MAX6018AEUR18+T, Voltage References Precision, Micropower, 1.8V Supply, Low-Dropout, SOT23 Voltage Reference

The MAX6018AEUR18+T is a precision, low dropout, micropower voltage reference in 3 pin SOT-23 package. This three terminal voltage reference operates with an input voltage ranging from (VOUT + 200mV) to 5.5V and 1.8V fixed output voltage. MAX6018AEUR18+T voltage reference consumes less than 5µA maximum of supply current and can source and sink up to 1mA of load current. It offers 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 device has an initial accuracy of 0.2% and temperature drift of ±16ppm/°C. The low dropout voltage, independent supply voltage and ultra low supply current makes this device ideal for two cell alkaline battery monitoring systems. • Operating temperature range from -40°C to 85°C• Maximum line regulation is 275µV/V at 1mA source current• Maximum load regulation is 800µV/mA• Supply voltage range from 2V to 5.5V• Quiescent supply current is 3µA at TA = 25°C• Maximum low dropout voltage is 200mV at 1mA load current
