Detailed Description
The MAX6018 is a precision, low-voltage, low-dropout,
Pin Description
micropower, bandgap voltage reference in a SOT23
package. This three-terminal reference operates with
an input voltage from (V OUT + 200mV) to 5.5V, and is
available with output voltage options of 1.2V, 1.6V,
1.8V, and 2.048V. These devices can source up to 1mA
with <200mV of dropout voltage, making them attrac-
tive for use in low-voltage applications.

FUNCTION
Supply Voltage Input. Bypass with a 0.1μF
capacitor to ground.
Reference Voltage Output. Bypass with at
least 100pF to ground. (See Output/Load
Capacitance section).
Ground
Output/Load Capacitance
These devices require a minimum of 100pF load to
maintain output stability.
They remain stable for capacitive loads as high as 1μF.
In applications where the load or the supply can experi-
ence step changes, a larger output capacitor reduces
the amount of overshoot (or undershoot) and assists
the circuit ’ s transient response. Otherwise, applications
may not need more than 100pF.
Supply Current
The 5μA maximum supply current varies only 0.1μA/V
with the supply voltage.
When the supply voltage is below the minimum-speci-
fied input voltage (as during turn-on), the devices 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
These devices typically turn on and settle to within
0.1% of their final value in 200μs. The turn-on time can
increase up to 1ms with the device operating at the
minimum dropout voltage and the maximum load.
