19-1613; Rev 3; 3/02 Low-Cost, Micropower, Low-Dropout,
High-Output-Current, SOT23 Voltage References
Features 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). ♦ Ultra-Small 3-Pin SOT23 Package 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. ♦ Low 75ppm/°C Temperature Coefficient The MAX6100–MAX6107 are available in tiny 3-pin
SOT23 packages. Applications
