Precision, Micropower, Low-Dropout, High-Output-Current, SOT23 Voltage References
General DescriptionThe MAX6061–MAX6068 are precision, low-dropout,
micropower voltage references. These three-terminal
devices 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 very
low temperature coefficient of 20ppm/°C (max) and an
initial accuracy of ±0.2% (max). Specifications apply to
the extended temperature range (-40°C to +85°C).
The MAX6061–MAX6068 typically draw only 90µA of
supply current and can source 5mA or 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
(8µA/V variation) and do not require an external resis-
tor. Additionally, the internally compensated devices do
not require an external compensation capacitor.
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 MAX6061–MAX6068 are available in a 3-pin SOT23
package.

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.
