Low-Cost, Micropower, Low-Dropout,
High-Output-Current, SOT23 Voltage References
General Description
Features
The MAX6100–MAX6107 are low-cost, low-dropout
(LDO), micropower voltage references. These three-ter-
minal 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 0.4ꢀ (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 compen-
sated 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. Low-
dropout voltage and supply independent, ultra-low sup-
ply current make these devices ideal for battery-operat-
ed, high-performance, low-voltage systems.
