Description

The MAX6103 is 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 circuitand 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).

The MAX6103 voltage references draw only 90A 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 resistor, these devices offer a supply current that is virtually independent of the supply voltage (with only a 4A/V variation with supply voltage) and do not require an external resistor. Additionally, these internally compensated 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. Lowdropout voltage and supply independent, ultra-low supply current makes MAX6103 ideal for battery-operated, high performance, low-voltage systems.

The MAX6103 is available in tiny 3-pin SOT23 packages.
