Low-Cost, Low-Power, Low-Dropout,
SOT23-3 Voltage References
General Description
The MAX6001–MAX6005 family of SOT23, low-cost
series voltage references meets the cost advantage of
shunt references and offers the power-saving advantage
of series references, which traditionally cost more. Unlike
conventional shunt-mode (two-terminal) references that
must be biased at the load current and require an exter-
nal resistor, these devices eliminate the need for an
external resistor and offer a supply current that is virtually
independent of the supply voltage.
These micropower, low-dropout, low-cost devices are
ideal for high-volume, cost-sensitive 3V and 5V battery-
operated systems with wide variations in supply voltage
that require very low power dissipation. Additionally,
these devices are internally compensated and do not
require an external compensation capacitor, saving
valuable board area in space-critical applications.

Turn-On Time
These devices typically turn on and settle to within
0.1% of their final value in 30µs to 220µs depending on
the device. The turn-on time can increase up to 1.5ms
with the device operating at the minimum dropout volt-
age and the maximum load.
Positive and Negative
Low-Power Voltage Reference
Figure 1 shows a typical method for developing a bipo-
lar reference. The circuit uses a MAX681 voltage dou-
bler/inverter charge-pump converter to power an
ICL7652, thus creating a positive as well as a negative
reference voltage.
