MAXIM MAX6100, MAX6107 Technical data

General 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 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 compen­sated 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. 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.

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.
