MAX6010
Precision, Micropower, 3V Series
Voltage Reference in SOT23
_______________________________________________________________________________________ 5
Detailed 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.
Applications Information
Output/Load Capacitance
The MAX6010 requires a minimum of 1nF load to main-
tain output stability.
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.
The input voltage source must be capable of providing
this current to ensure reliable turn-on.
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.
