PRODUCT DESCRIPTION
The SPX4040 is a two-terminal, temperature compensated, band-gap voltage reference, which provides a fixed 2.5V output for input
currents between 100 µA to 15mA. The bandgap voltage (2.5V) is independently trimmed from the output voltage to achieve a very
low tempco. This trimming technique process gives a very stable device over the full temperature range (A grade 50 ppm/ °C). The
SPX4040 is available in the sub-miniature (3mm × 1.3mm) SOT-23, SO-8 surface mount package, or TO-92 package. The operating
temperature is -40°C to 85°C.
The SPX4040 advanced design eliminates the need for an external stabilized capacitor while insuring stability with any capacitive
load, making them easy to use.

Note:
1) Three-point measurement guarantees the error band over the specified temperature range.
2) Optimum performance is obtained at currents below 1000 µA.
3) Limits are 100% production tested at 25°C. Limits over temperature are guaranteed through correlation using statistical quality control.

SPX4040 Applications Hints
This device is designed for stable operation and has no need
of an external capacitor between pin 4 and 8. The reference
remains stable if a bypass capacitor is used.
Figure 1. SPX4040 Fixed
Shunt Regulator Application
SOT-23
The SPX4040 in the SOT-23 package has a parasitic
Schottky diode between pin 3 and pin 1. Pin 1 of SOT-23
must float or be connected to pin 3.
VS
Conventional Shunt Regulator
RS
VR
IO + IL
IL
In a conventional shunt regulator application (see Figure 1),
an external series resister (RS) is connected between the
supply voltage and the SPX4040. RS determines the current
that flows through the load (IL) and the reference(IQ). Since
load current and supply voltage may vary, RS should be small
enough to supply at least the minimum acceptable IQ to the
reference 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
SPX4040 is less than 15mA
VO
IQ
SPX4040
RS is determined by the supply voltage (VS), the load and
operating current (IL and IQ), reference’s reverse breakdown
voltage (VR).
RS = (VS - VR)/(IL+IQ)
