High-Output-Current, SOT23 Voltage References
General Description
The MAX6101–MAX6105 are low-cost, low-dropout
(LDO), micropower voltage references. These three-termi-
nal references operate with an input voltage range from
(VOUT + 200mV) to 12.6V and are available with output
voltage options of 1.25V, 2.5V, 3V, 4.096V, and 5V. They
feature a proprietary curvature-correction circuit and
laser-trimmed thin-film resistors that result in a low tem-
perature 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 compensat-
ed devices do not require an external compensation
capacitor and are stable with up to 1µF of load capaci-
tance. Eliminating the external compensation capacitor
saves valuable board area in space-critical applications.
Their LDO voltage and supply-independent, ultra-low
supply current make these devices ideal for battery-oper-
ated, high-performance, low-voltage systems.
The MAX6101–MAX6105 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.
