MAX6100
19-1613; Rev 3; 3/02
Low-Cost, Micropower, Low-Dropout,
High-Output-Current, SOT23 Voltage References
General Description
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 ±0.4% (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 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.
The MAX6100–MAX6107 are available in tiny 3-pin
SOT23 packages.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
