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).
