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.

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.

Conventional Shunt Regulator

In a conventional shunt regulator application (see Figure 1),
an external series resister (R
