LM4041DYM3-ADJ-TR

Microchip Tech · Voltage Reference · SOT-23

LM4041DYM3-ADJ-TR from Microchip Tech, 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 FB input Feedback pin: connect to a resistive divider network to set the output voltage.
2 + passive Cathode: connect to positive voltage.
3 - power_in Anode: connect to negative voltage; on the LM4041-ADJ, pin 3 is the (-) output terminal.
