3ppm/°C, Low-Power, Low-Dropout
Voltage Reference
General Description
Features
The MAX6133 high-precision, low-power, low-dropout
voltage reference features a low 3ppm/°C (max) temper-
ature coefficient and a low dropout voltage (200mV,
max). This series-mode device features bandgap tech-
nology for low-noise performance and excellent accura-
cy. Load regulation specifications are guaranteed for
source currents up to 15mA. The laser-trimmed, high-
stability thin-film resistors, together with post-package
trimming, guarantee an excellent initial accuracy specifi-
cation (0.04%, max). The MAX6133 is a series voltage
reference and consumes only 40µA of supply current
(virtually independent of supply voltage). Series-mode
references save system power and use minimal external
components compared to 2-terminal shunt references.
o Low Temperature Coefficient
3ppm/°C (max), SO
5ppm/°C (max), µMAX
o Tiny 5mm ✕ 3mm µMAX Package
o Low 200mV (max) Dropout Voltage
o Low 40µA Quiescent Current
o

o 15mA Output Source-Current Capability
o Wide 2ꢀ7V to 12ꢀ6V Supply Voltage
The MAX6133 is available in 8-pin µMAX and SO pack-
ages. The unique blend of tiny packaging and excellent
precision performance make these parts ideally suited
for portable and communication applications.
o Excellent Line (30µV/V, max) and

Note 4: Many of the MAX6133 Typical Operating Characteristics are extremely similar. The extremes of these characteristics are
found in the MAX6133 (2.5V output) and the MAX6133 (5V output). The Typical Operating Characteristics of the remainder
of the MAX6133 family typically lie between these two extremes and can be estimated based on their output voltages.

Turn-On Time
Applications Information
These devices typically turn on and settle to within
0.01% of their final value in <1ms. The turn-on time can
increase up to 2ms with the device operating at the
minimum dropout voltage and the maximum load.
Bypassing/Load Capacitance
For the best line-transient performance, decouple the
input with a 0.1µF ceramic capacitor as shown in the
Typical Operating Circuit. Place the capacitor as close
to IN as possible. When transient performance is less
important, no capacitor is necessary. The MAX6133
family requires a minimum output capacitance of 0.1µF
for stability and is stable with capacitive loads (includ-
ing the bypass capacitance) of up to 100µF. In applica-
tions where the load or the supply can experience step
changes, a larger output capacitor reduces the amount
of overshoot (undershoot) and improves the circuit’s
transient response. Place output capacitors as close to
the device as possible.
Low-Power, 14-Bit DAC
with MAX6133 as a Reference
Figure 1 shows a typical application circuit for the
MAX6133 providing both the power supply and precision
reference voltage for a 14-bit high-resolution, serial-
input, voltage-output digital-to-analog converter. The
MAX6133 with a 2.5V output provides the reference volt-
age for the DAC.
Supply Current
The quiescent supply current of the MAX6133 series
reference is typically 40µA and is virtually independent
of the supply voltage. In the MAX6133 family, the load
current is drawn from the input only when required, so
supply current is not wasted and efficiency is maxi-
mized at all input voltages. This improved efficiency
reduces power dissipation and extends battery life.
When the supply voltage is below the minimum-speci-
fied input voltage (as during turn-on), the devices can
draw up to 150µA beyond the nominal supply current.
The input voltage source must be capable of providing
this current to ensure reliable turn-on.

Thermal Hysteresis
Thermal hysteresis is the change in the output voltage
at T = +25°C before and after the device is cycled
A
over its entire operating temperature range. Hysteresis
is caused by differential package stress appearing
across the bandgap core transistors. The typical ther-
mal hysteresis value is 120ppm for both SO and µMAX
packages.

Temperature Coefficient vs.
Operating Temperature Range
As shown in Figure 2, the MAX6133 can be used to
develop a negative voltage reference using the
MAX400, a rail-to-rail op-amp with low power, low
noise, and low offset. The circuit only provides a good
negative reference and is ideal for space- and cost-
sensitive applications since it does not use resistors.
for a 1LSB Maximum Error
In a data converter application, the converter’s refer-
ence voltage must stay within a certain limit to keep the
error in the data converter smaller than the resolution
limit through the operating temperature range. Figure 3
shows the maximum allowable reference-voltage tem-
perature coefficient that keeps the conversion error to
less than 1LSB. This is a function of the operating tem-
POSITIVE SUPPLY
perature range (T
- T ) with the converter resolu-
MIN
MAX
tion as a parameter. The graph assumes the
reference-voltage temperature coefficient as the only
parameter affecting accuracy. In reality, the absolute
static accuracy of a data converter is dependent on the
combination of many parameters such as integral non-
linearity, differential nonlinearity, offset error, gain error,
as well as voltage reference changes.
