LM4040BIM3X-10

Texas Instruments · Voltage Reference · SOT-23-3

LM4040BIM3X-10 from Texas Instruments, in a SOT-23-3. 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 bidirectional Cathode is the parallel current / regulated output voltage pin (Table 4-1 lists it as I/O), and the reverse current must stay between IRMIN (100 µA for the 10 V version) and IRMAX (15 mA) through an external series resistor.
2 Anode output Anode pin is normally grounded, and the absolute maximum reverse current is 20 mA and forward current is 10 mA.
3 * unconnected Pin 3 must be left floating or connected to the anode (pin 2) because of a parasitic Schottky diode between pins 2 and 3; TI recommends connecting it to the anode in applications with high EMI or significant high-frequency switching noise.
