MAX6012/6021/6025/ Precision, Low-Power, Low-Dropout, 6030/6041/6045/6050 SOT23-3 Voltage References General Description Features The MAX6012/MAX6021/MAX6025/MAX6030/MAX6041/ 0.2% (max) Initial Accuracy MAX6045/MAX6050 precision, low-dropout, micropower 15ppm/C (max) Temperature Coefficient voltage references are available in miniature SOT23-3 35A (max) Quiescent Supply Current surface-mount packages. They feature a proprietary curvature-correction circuit and laser-trimmed thin-film 0.8A/V Supply Current Variation with V IN resistors that result in a low temperature coefficient of 500A Output Source and Sink Current <15ppm/C and initial accuracy of better than 0.2%. 100mV Dropout at 500A Load Current These devices are specified over the extended tempera- 0.12V/A Load Regulation ture range. 8V/V Line Regulation These series-mode voltage references draw only 27A of quiescent supply current and can sink or source up to Stable with C = 0 to 2.2nF LOAD 500A of load current. Unlike conventional shunt-mode (two-terminal) references that waste supply current and Ordering Information require an external resistor, devices in the MAX6012 PIN- TOP family offer a supply current thats virtually independent PART TEMP RANGE PACKAGE MARK of supply voltage (with only a 0.8A/V variation with supply voltage) and do not require an external resistor.
