The MAX6161–MAX6168 are precision, low-dropout,
micropower voltage references. These three-terminal

♦ ±2ꢃVSnIkVCcuueIiVꢀiV±.52m/2ꢃ
devices operate with an input voltage range from (V
OUT
+ 200mV) to 12.6V and are available with output volt-
age options of 1.25V, 1.8V, 2.048V, 2.5V, 3V, 4.096V,
4.5V, and 5V. They feature a proprietary curvature-cor-
rection circuit and laser-trimmed thin-film resistors that
result in a very low temperature coefficient of 5ppm/°C
(max) and an initial accuracy of 2mV (max).
Specifications apply to the extended temperature range
(-40°C to +85°C).

The MAX6161–MAX6168 typically draw only 100µA of
supply current and can source 5mA (4mA for
MAX6161) or sink 2mA of load current. Unlike conven-
tional shunt-mode (two-terminal) references that waste
supply current and require an external resistor, these
devices offer a supply current that is virtually indepen-
dent of the supply voltage (8µA/V variation) and do not
require an external resistor. Additionally, the internally
compensated devices do not require an external com-
pensation capacitor. Eliminating the external compen-
sation capacitor saves valuable board area in
space-critical applications. A low-dropout voltage and
a supply-independent, ultra-low supply current make
these devices ideal for battery-operated, high-perfor-
mance, low-voltage systems.

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.

NoieV5: Many of the Typical Operating Characteristics of the MAX6161 family are extremely similar. The extremes of these characteristics
are found in the MAX6161 (1.25V output) and the MAX6165 (5.0V output). The Typical Operating Characteristics of the remain-
der of the MAX6161 family typically lie between these two extremes and can be estimated based on their output voltages.

Applications Information
Output voltage hysteresis is the change in the input

For the best line-transient performance, decouple the
input with a 0.1µF ceramic capacitor as shown in the
Typical Operating Circuit. Locate the capacitor as
close to IN as possible. When transient performance is
less important, no capacitor is necessary.
cycled over its entire operating temperature range.
Hysteresis is caused by differential package stress
appearing across the bandgap core transistors. The
typical temperature hysteresis value is 125ppm.
Turn-On Time
These devices typically turn on and settle to within
0.1% of their final value in 50µs to 300µs, depending on
the output voltage (see electrical table of part used).
The turn-on time can increase up to 1.5ms with the
device operating at the minimum dropout voltage and
the maximum load.
Output/Load Capacitance
Devices in the MAX6161 family do not require an output
capacitor for frequency stability. In applications where
the load or the supply can experience step changes,
an output capacitor of at least 0.1µF will reduce the
amount of overshoot (undershoot) and improve the cir-
cuit’s transient response. Many applications do not
require an external capacitor, and the MAX6161 family
can offer a significant advantage in applications when
board space is critical.
Typical Operating Circuit
Supply Current
The quiescent supply current of the series-mode
MAX6161 family is typically 100µA and is virtually inde-
pendent of the supply voltage, with only an 8µA/V
(max) variation with supply voltage. Unlike series refer-
ences, shunt-mode references operate with a series
resistor connected to the power supply. The quiescent
current of a shunt-mode reference is thus a function of
the input voltage. Additionally, shunt-mode references
have to be biased at the maximum expected load cur-
rent, even if the load current is not present at the time.
In the MAX6161 family, the load current is drawn from
the input voltage only when required, so supply current
is not wasted and efficiency is maximized at all input
voltages. This improved efficiency reduces power dissi-
pation and extends battery life.

*CAPACITORS ARE OPTIONAL.
When the supply voltage is below the minimum speci-
fied input voltage (as during turn-on), the devices can
draw up to 400µA beyond the nominal supply current.
The input voltage source must be capable of providing
this current to ensure reliable turn-on.
