MAXIM INTEGRATED / ANALOG DEVICES LM4040DIM325T Precision Voltage Reference

The LM4040DIM3-2.5+T is a compact precision shunt voltage reference in a 3-pin SOT-23 package, offering a stable 2.5V output with high accuracy of 1%. It uses laser-trimmed resistors to ensure initial accuracy and boasts a low temperature coefficient of ±20ppm/°C at 10mA. Capable of operating with a minimum shunt current of 45μA, it maintains stable voltage regulation across -40°C to 85°C without external stabilization capacitors. Its low output noise (35μVrms from 10Hz to 10kHz) and low dynamic impedance make it ideal for power management, portable electronics, and industrial systems.
