These three-ter- minal references are available with output voltage options of 1.25V, 1.8V, 2.048V, 2.5V, 3V, 4.096V, 4.5V, and 5V. They feature a proprietary curvature-correction circuit and laser-trimmed, thin-film resistors that result in a low temperature coefficient of 75ppm/°C (max) and an initial accuracy of ±0.4% (max). These devices are specified over the extended temperature range (-40°C to +85°C). These series-mode voltage references draw only 90µA of supply current and can source 5mA and sink 2mA of load current. Unlike conventional shunt-mode (two-terminal) references that waste supply current and require an external resistor, these devices offer a supply current that is virtually independent of the supply voltage (with only a 4µA/V variation with supply voltage) and do not require an external resistor. Additionally, these internally compen- sated devices do not require an external compensation capacitor and are stable with load capacitance. Eliminating the external compensation capacitor saves valuable board area in space-critical applications. Low- dropout voltage and supply independent, ultra-low sup- ply current make these devices ideal for battery-operat- ed, high-performance, low-voltage systems. The MAX6100–MAX6107 are available in tiny 3-pin SOT23 packages.
