LM4041QAIM3-1.2

Texas Instruments · Voltage Reference · SOT-23-3

LM4041QAIM3-1.2 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 − bidirectional Cathode pin that shunts the regulated current and provides the output voltage; the 1.2 V version's recommended reverse current is 60 µA to 12000 µA (LM4041-N 1.2 row, Section 5.3).
2 + power_in Anode pin, normally connected to ground, serving as the reference terminal for the reverse-breakdown voltage.
3 NC* unconnected Must be left floating or connected to the anode; TI recommends connecting it to the anode in applications with high EMI or significant high-frequency switching noise.
