MAX6100MAX6107 19-1613 Rev 3 3/02 Low-Cost, Micropower, Low-Dropout, High-Output-Current, SOT23 Voltage References General Description Features The MAX6100MAX6107 are low-cost, low-dropout Ultra-Small 3-Pin SOT23 Package (LDO), micropower voltage references. These three-ter- Low Cost minal references are available with output voltage options of 1.25V, 1.8V, 2.048V, 2.5V, 3V, 4.096V, 4.5V, and 5V. No Output Capacitor Required They feature a proprietary curvature-correction circuit Stable with Capacitive Loads and laser-trimmed, thin-film resistors that result in a low Load Regulation (2mA Sink): 8mV/mA (max) temperature coefficient of 75ppm/C (max) and an initial accuracy of 0.4% (max). These devices are specified Load Regulation (5mA Source): 0.9mV/mA (max) over the extended temperature range (-40C to +85C). 0.4% (max) Initial Accuracy These series-mode voltage references draw only 90A of Low 75ppm/C Temperature Coefficient supply current and can source 5mA and sink 2mA of load current. Unlike conventional shunt-mode (two-terminal) 125A (max) Quiescent Supply Current references that waste supply current and require an 50mV Dropout at 1mA Load Current external 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 compen- Ordering Information sated devices do not require an external compensation PIN- TOP capacitor and are stable with load capacitance. PART TEMP RANGE PACKAGE MARK Eliminating the external compensation capacitor saves MAX6100EUR-T -40C to +85C 3 SOT23-3 FZID valuable board area in space-critical applications.
