The LM4040DEM3-2.5 is a precision micropower shunt voltage reference from Quarktwin Technology Ltd., designed for applications requiring a stable 2.5V output. It features a maximum output voltage tolerance of ¬±0.1% at 25¬8C and operates within a wide current range of 60 OºA to 15 mA. The device is available in a compact SOT-23 package, making it suitable for space-constrained designs. It does not require an external stabilizing capacitor and can tolerate capacitive loads, simplifying integration into various circuits. The LM4040DEM3-2.5 operates over an industrial temperature range of -40¬8C to +85¬8C, with a low temperature coefficient of 100 ppm/¬8C maximum. This voltage reference is ideal for applications in portable battery-powered equipment, data acquisition systems, and instrumentation.
