AS4040 General Description


The AS4040 is a two-terminal, temperature compensated, band-gap voltage reference, which provides a fixed 2.5V output for input currents between 100 A 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 AS4040 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 AS4040 advanced design eliminates the need for an external stabilized capacitor while insuring stability with any capacitive load, making them easy to use.
