MAX6107 Datasheet | Maxim Integrated

Description The MAX6100- MAX6107 are low-cost, low-dropout (LDO), micropower voltage references. These three-terminal 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 5m A and sink 2m A 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 pensated devices do not require an external pensation capacitor and are stable with load capacitance. Eliminating the external pensation capacitor saves valuable board area in space-critical applications. Lowdropout voltage and supply independent, ultra-low supply current make these devices ideal for battery-operated, high-performance, low-voltage systems. The MAX6100- MAX6107 are available in tiny 3-pin SOT23 packages.
