Precision, Low-Power, Low-Dropout, SOT23-3 Voltage References
General Description
The MAX6012/MAX6021/MAX6025/MAX6030/MAX6041/ MAX6045/MAX6050 precision, low-dropout, micropower voltage references are available in miniature SOT23-3 surface-mount packages. They feature a proprietary curvature-correction circuit and laser-trimmed thin-film resistors that result in a low temperature coefficient of <15ppm/°C and initial accuracy of better than 0.2%. These devices are specified over the extended temperature range. These series-mode voltage references draw only 27µA of quiescent supply current and can sink or source up to 500µA of load current. Unlike conventional shuntmode (two-terminal) references that waste supply current and require an external resistor, devices in the MAX601 2 family offer a supply current that's virtually independent of supply voltage (with only a 0.8µA/V variation with supply voltage) and do not require an external r e s i s t o r . Additionally, these internally compensated d e v i c e s do not require an external compensation capacitor and are stable with up to 2.2nF of load capacitance. Eliminating the external compensation capacitor saves valuable board area in space-critical applications. T h e i r low dropout voltage and supply-independent, ultra-low supply current make these devices ideal for battery-operated, low-voltage systems. o 0.2% (max) Initial Accuracy o 15ppm/°C (max) Temperature Coefficient o 35µA (max) Quiescent Supply Current o 0.8µA/V Supply Current Variation with VIN o ±500µA Output Source and Sink Current o 100mV Dropout at 500µA Load Current o 0.12µV/µA Load Regulation o 8µV/V Line Regulation o Stable with CLOAD = 0 to 2.2nF
