LM4040C25QDBZT

Texas Instruments · Voltage Reference · SOT-23

LM4040C25QDBZT from Texas Instruments, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 CATHODE output Fixed 2.5V shunt voltage reference output with 0.5% initial accuracy and 100ppm/°C temperature coefficient; operating range -40°C to 125°C; minimum operating current 60µA, maximum 15mA.
2 ANODE power_in Ground return connection; typically connected to circuit ground.
3 * passive Parasitic suppression node connected via internal Schottky diode to anode (pin 2); must be left floating or connected to anode for noise immunity in high-EMI or high-frequency switching applications.
