MAX6101

19-1613; Rev 0; 1/00 Low-Cost, Micropower, Low-Dropout, High-Output-Current, SOT23 Voltage References General Description The MAX6101–MAX6105 are low-cost, low-dropout (LDO), micropower voltage references. These three-terminal references operate with an input voltage range from (VOUT + 200mV) to 12.6V and are available with output voltage options of 1.25V, 2.5V, 3V, 4.096V, 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 up to 1µF of load capacitance. Eliminating the external compensation capacitor saves valuable board area in space-critical applications. Their LDO voltage and supply-independent, ultra-low supply current make these devices ideal for battery-operated, high-performance, low-voltage systems. The MAX6...
