MAX6061–MAX6068
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 resistor. 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 supply current make these devices ideal for battery-operated, high-performance, low-voltage systems.
The MAX6061–MAX6068 are available in a 3-pin SOT23
package.

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.

All devices are 100% production tested at TA = +25°C and are guaranteed by design for TA = TMIN to TMAX, as specified.
Temperature Coefficient is measured by the “box” method, i.e., the maximum ∆VOUT is divided by the maximum ∆T.
Temperature Hysteresis is defined as the change in +25°C output voltage before and after cycling the device from TMIN to TMAX.
Dropout voltage is the minimum input voltage at which VOUT changes ≤ 0.2% from VOUT at VIN = 5.0V (VIN = 5.5V for MAX6065).

Note 5: Many of the MAX6061 family Typical Operating Characteristics are extremely similar. The extremes of these characteristics
are found in the MAX6061 (1.25V output) and the MAX6065 (5.0V output). The Typical Operating Characteristics of the
remainder of the MAX6061 family, typically lie between these two extremes and can be estimated based on their output
voltages.

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 MAX6061 family do not require an output
capacitance 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 circuit’s transient response. Many applications do not require an external capacitor, and the
MAX6061 family can offer a significant advantage in
these applications when board space is critical.
Supply Current
The quiescent supply current of the series-mode
MAX6061 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
MAX6061 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 TA = +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, depending on the
device. The turn-on time can increase up to 1.5ms with
the device operating at the minimum dropout voltage and
the maximum load.
