Precision, Micropower, Low-Dropout Voltage References
General Description
The MAX6190MAX6195/MAX6198 precision, micropower, low-dropout voltage references offer high initial accuracy and very low temperature coefficient through a proprietary curvature-correction circuit and lasertrimmed precision thin-film resistors. These series-mode bandgap references draw a maximum of only 35µA quiescent supply current, making them ideal for battery-powered instruments. They offer a supply current that is virtually immune to input volta g e variations. Load-regulation specifications are guaranteed for source and sink currents up to 500µA. T h e s e devices are internally compensated, making them ideal for applications that require fast settling, and are stable with capacitive loads up to 2.2nF. o ±2mV (max) Initial Accuracy o 5ppm/°C (max) Temperature Coefficient o 35µA (max) Supply Current o 100mV Dropout at 500µA Load Current o 0.12µV/µA Load Regulation o 8µV/V Line Regulation

Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
