Precision, Micropower, Low-Dropout,
High-Output-Current, SOT23 Voltage References
General Description
The 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.
