Applications Information
The LM4431 is a micro-power curvature-corrected 2.5V
bandgap shunt voltage reference. For space critical applica-
tions, the LM4431 is available in the sub-miniature SOT-23
surface-mount package. The LM4431 has been designed for
stable operation without the need of an external capacitor
connected between the “+” pin and the “−” pin. If, however, a
bypass capacitor is used, the LM4431 remains stable. The
operating current range is 100 µA to 15 mA.
The LM4431’s SOT-23 package has a parasitic Schottky di-
ode between pin 2 (−) and pin 3 (Die attach interface con-
tact). Therefore, pin 3 of the SOT-23 package must be left
floating or connected to pin 2.
In a conventional shunt regulator application (
Figure 1),an
external series resistor (R
S) is connected between the sup-
ply voltage and the LM4431. R
S determines the current that
flows through the load (I
L) and the LM4431 (IQ). Since load
current and supply voltage may vary, R
S should be small
enough to supply at least the minimum acceptable I
Q to the
LM4431 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 I
L is at its minimum, RS should
be large enough so that the current flowing through the
LM4431 is less than 15 mA.
R
S is determined by the supply voltage, (VS), the load and
operating current, (I
L and IQ), and the LM4431’s reverse
breakdown voltage, V
R.
