Precision, Micropower, 3V Series
Voltage Reference in SOT23
MAX610
General Description
Features
The MAX6010 is a precision, low-noise, low-dropout,
micropower voltage reference in a SOT23 package. This
three-terminal voltage reference operates with an input
voltage from 3.2V to 5.5V, and outputs 3V.
o Ultra-Low Supply Current: 5µA (max)
o 3V Output from 3.2V Input
o Small, 3-Pin SOT23 Package
o Initial Accuracy: 0.2% (max)
o Low Temperature Drift: 50ppm/°C (max)
o 200mV Dropout Voltage
The MAX6010 voltage reference consumes less than
5µA (max) of supply current and can source up to 7mA
and sink up to 1mA of load current when the input is
5V. Unlike conventional shunt-mode (two-terminal) ref-
erences that waste supply current and require an exter-
nal resistor, the MAX6010 offers a supply current that is
virtually independent of supply voltage (with only
0.05µA/V variation with supply voltage) and does not
require an external resistor. The MAX6010 has initial
accuracies of 0.2% (A grade) and 0.4% (B grade) and
a temperature drift of 50ppm/°C (max). The low-dropout
voltage and the ultra-low supply current over the full
voltage range make this device ideal for portable and
battery-operated applications. The MAX6010 is avail-
able in a small, 3-pin SOT23 package.
o Load Regulation (7mA Source): 200µV/mA (max)
o Line Regulation 3.2V to 5.5V: 350µV/V (max)

Detailed Description
Pin Description
The MAX6010 is a precision, low-noise, low-dropout,
micropower, bandgap voltage reference in a SOT23
package. This three-terminal reference operates with
an input voltage from 3.2V to 5.5V, and outputs 3V. The
device sources up to 7mA with < 200mV of dropout
voltage and requires only 5µA (max) supply current.

IN
Supply Voltage Input
Reference Voltage Output. Bypass with at
least 1nF to ground. (See the Output/Load
Capacitance section.)

3
OUT
GND
Ground
Applications Information
The input voltage source must be capable of providing
this current to ensure reliable turn-on.
Output/Load Capacitance
The MAX6010 requires a minimum of 1nF load to main-
tain output stability.
Turn-On Time
The MAX6010 typically turns on and settles to within
0.1% of the final value in 700µs. The turn-on time can
increase with the device operating at the minimum
dropout voltage and the maximum load.
The device remains stable for capacitive loads as high
as 1µF. In applications where the load or the supply
can experience step changes, a larger output capaci-
tor reduces the amount of overshoot (or undershoot)
and assists the circuit’s transient response.
Supply Current
The 5µA maximum supply current varies only 0.05µA/V
with the supply voltage.
When the supply voltage is below the minimum-speci-
fied input voltage (as during turn-on), the device can
draw up to 20µA beyond the nominal supply current.
