The fixed output version is available in 0.5% C grade and 1% D grade
while the adjustable is only available in D grade. Excellent
performance is maintained over the 60µA to 12mA operating current
range with a typical temperature coefficient of only 20ppm/°C. The
device has been designed to be highly tolerant of capacitive loads so
maintaining excellent stability.

LM4041Q
Application Information
The LM4041Q comes in two variants:
LM4041_Q with fixed 1.225V output
LM4041DADJQ with variable output voltage.
In a conventional shunt reference (2-terminal, fixed output device) application (Figure 1), an external
series resistor (RS) is connected between the supply voltage, VS, and the LM4041Q.
RS determines the current that flows through the load (IL) and the LM4041Q (IR). Since load current and
supply voltage may vary, RS should be small enough to supply at least the minimum acceptable IR to the
LM4041Q even when the supply voltage is at its minimum and the load current is at its maximum value.
When the supply voltage is at its maximum and IL is at its minimum, RS should be large enough so that
the current flowing through the LM4041Q is less than 12 mA.
RS is determined by the supply voltage, (VS), the load and operating current, (IL and IQ), and the
LM4041Q’s reverse breakdown voltage, VR.
VS VR
IL IR
RS
For the adjustable device 3-terminals are used
VS
The LM4041Q-ADJ’s output voltage can be adjusted to any value in the range of 1.24V through 10V. The
output voltage is set by the ratio of two external feedback resistors as shown in Figure 2 and the internal
reference voltage (VR).

The output voltage is found using the equation:

Printed Circuit Board Layout Considerations
LM4041Q with fixed output voltage in the SOT23 package has the die attached to pin 3, which results in an electrical contact between pin 2 and
pin 3.
Therefore, pin 3 of the SOT23 package must be left floating or connected to pin 2.
