DESCRIPTION
The SPX4040 is a 2-terminal, temperature compensated, bandgap voltage reference that
provides a fixed 2.5V output for input currents between 160µA and 15mA. The bandgap voltage
(2.5V) is independently trimmed from the output voltage to achive a very low temperature
coefficient. This trimming technique gives a stable device over the full temperature range
(100ppm/°C).
The SPX4040 is available in 3 pin TO-92, 3 SOT-23 and 8 pin NSOIC packages. The operating
temperature range is -40°C to 85°C. The SPX4040 advanced design eliminates the need for an
external stabilizing capacitor while ensuring stability with any capacitive load, making it easy to
use.
