Precision, Low-Power, Low-Dropout, MAX6012/MAX6021/MAX6025/MAX6030/ SOT23-3 Voltage References MAX6041/MAX6045/MAX6050 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 ● 35μA (max) Quiescent Supply Current surface-mount packages. They feature a proprietary ● 0.8μA/V Supply Current Variation with V curvature-correction circuit and laser-trimmed thin-film IN 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%. ● 100mV Dropout at 500μA Load Current These devices are specified over the extended tempera- ● 0.12μV/μA Load Regulation ture range. ● 8μV/V Line Regulation These series-mode voltage references draw only 27μA ● Stable with CLOAD = 0 to 2.2nF of quiescent supply current and can sink or source up to
