General Description
The MAX6100–MAX6107 are low-cost, low-dropout
(LDO), micropower voltage references. These three-terminal references 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 low
temperature coefficient of 75ppm/°C (max) and an initial
accuracy of ±0.4% (max). These devices are specified
over the extended temperature range (-40°C to +85°C).
These series-mode voltage references draw only 90µA of
supply current and can source 5mA and 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 (with only a
4µA/V variation with supply voltage) and do not require
an external resistor. Additionally, these internally compensated devices do not require an external compensation
capacitor and are stable with load capacitance.
Eliminating the external compensation capacitor saves
valuable board area in space-critical applications. Lowdropout voltage and supply independent, ultra-low supply current make these devices ideal for battery-operated, high-performance, low-voltage systems.
The MAX6100–MAX6107 are available in tiny 3-pin
SOT23 packages.

by correlation to
sample units characterized over temperature.
Note 2: Temperature coefficient is specified by the “box” method, i.e., the maximum ∆V
OUT
is divided by the maximum ∆t.
Note 3: Not production tested. Guaranteed by design.
Note 4: Thermal hysteresis is defined as the change in +25°C output voltage before and after temperature cycling of the device
from T
A

Note 5: Dropout voltage is the minimum input voltage at which V

Applications Information
Input Bypassing
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. Where transient performance is less
important, no capacitor is necessary.
Output/Load Capacitance
Devices in the MAX6100 family do not require an output
capacitance for frequency stability. They are stable for
any capacitive load when sourcing less than 200µA.
When sourcing greater than 200µA, the output may
become unstable with capacitive loads between 0.5nF
and 50nF. In applications where the load or the supply
can experience step changes, an output capacitor
reduces the amount of overshoot (undershoot) and
improves the circuit’s transient response. Many applications do not require an external capacitor, and the
MAX6100 family can offer a significant advantage in
these applications when board space is critical.
Supply Current
The quiescent supply current of the series-mode
MAX6100 family is typically 90µA and is virtually independent of the supply voltage, with only an 8µA/V (max) variation with supply voltage. Unlike series references,
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 current, even if the
load current is not present at the time. In the MAX6100
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 dissipation and
extends battery life. When the supply voltage is below the
minimum specified 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.
Output Voltage Hysteresis
Output voltage hysteresis is the change of output voltage
at T
A
= +25°C before and after the device is 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 130ppm.

Turn-On Time
These devices typically turn on and settle to within 0.1%
of their final value in 50µs to 300µs. The turn-on time can
increase up to 1.5ms with the device operating at the
minimum dropout voltage and the maximum load.
