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.
