which is also the nearest 0.1% resistor value.
Choose R2 according to the following equation:
R2 = R1 / (V OUT / V ADJ - 1)
For example, a 2.5V output requires R1 = (1.06 x 10 5 )
(2.5V / 1.23V) ≈ 215k ? , which is the nearest standard-
value 0.1% resistor.

_____________Applications Information
Setting the MAX6160 Output Voltage
Set the output voltage on the MAX6160 by connecting
a resistor divider between OUT, ADJ, and GND
(Figure 1). Choose R1 according to the following equa-
tion:
R1 = (1.06 x 10 5 ) (V OUT / V ADJ ) ?
where V TH = 1.23V. The scaling factor (1.06 x 10 5 )
compensates for the MAX6160's change in ADJ input
current over temperature. When R1 is chosen correctly,
the change in voltage across R1 caused by the ADJ
input current is properly cancelled. Choose R1 to within
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 the device pin as possible. Where transient
performance is less important, no capacitor is
necessary.
Output Bypassing
The MAX6125/MAX6141/MAX6145/MAX6150/MAX6160
do not require an output capacitor. They are stable for
capacitive loads from 0nF to 10nF. If your application
requires an output charge reservoir (e.g., to decouple
the reference from a DAC’s input), then make sure that
the total output capacitive load does not exceed 10nF
for optimum settling-time performance.
