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 surface-mount packages. They feature a proprietary ● 35μA (max) Quiescent Supply Current curvature-correction circuit and laser-trimmed thin-film ● 0.8μA/V Supply Current Variation with VIN resistors that result in a low temperature coefficient of ● ±500μA Output Source and Sink Current <15ppm/°C and initial accuracy of better than 0.2%. These devices are specified over the extended tempera- ● 100mV Dropout at 500μA Load Current ture range. ● 0.12μV/μA Load Regulation These series-mode voltage references draw only 27μA ● 8μV/V Line Regulation of quiescent supply current and can sink or source up to ● Stable with CLOAD = 0 to 2.2nF 500μA of load current. Unlike conventional shunt-mode (two-terminal) references that waste supply current and
