General Description The MAX6100 - MAX6107 are low-cost, low-dropout (LDO) regulators, micropower voltage references. These three terminals are available for reference output voltage options of 1.25V, 1.8V and 2.048V, 2.5V and 3V, 4.096V, 4.5V, and 5V. They feature proprietary curvature correction circuitry and laser trimming, thin-film resistors, and thus 75ppm/°C (max) coefficients at low temperatures 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 are formulated with only 90µA supply current at 5mA, and source and sink loads at 2mA. Unlike traditional parallel mode (2-terminal) references that waste supply current and require an external resistor, these devices provide supply current that is virtually independent of supply voltage (only a 4µA/V supply voltage variation) and does not require an external resistor device. In addition, these internal compensation devices do not require external compensation capacitors and load capacitors for stabilization. Eliminating external compensation capacitors saves valuable board area in space-constrained applications. Lowdropout voltage and power supply independence, ultra-low supply current makes these devices ideal for battery-operated, high-performance, low-voltage systems. The MAX6100 - MAX6107 are available in the small three-pin SOT23 package.
