QUAD LOW NOISE HIGH PSRR
LINEAR VOLTAGE REGULATOR
Output Voltage Adjust
There are several ways to adjust the output voltage for each regulator. A 5V setting for any output can be achieved
by grounding the respective HVx (x=1,2,3,4) pin. Any other value requires an external resistor, connected between
RDx and GND for a voltage higher than the default, or between VRx and RDx for a voltage lower than the default. The
figures below show the values of the internal resistive dividers that set the default output voltage a. for 3V and b. for
4.5V and two examples of two different voltage settings: c. shows a default 3V output changed to 3.3V by connecting
a 220k Ohm resistor between RDx and GND, while d. shows the same output adjusted to 2.5V by connecting a 120k
Ohm resistor between VRx and RDx.
The internal resistors have a temperature coefficient (TempCo) of +270ppm/°C. When the default output voltage
is modified by using an external resistor with a different TempCo, the temperature behavior of the respective output
will differ from this specification, although the difference will likely be very small.
