LM4041DADJFTA

Diodes Incorporated · Voltage Reference · SOT-23

LM4041DADJFTA from Diodes Incorporated, 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 REF input Reference input of the adjustable LM4041-ADJ, where the output voltage is set by the ratio of two external feedback resistors and the internal reference voltage VR (1.233 V typ at 25 °C); reference input current IREF is 200 nA max over -40 to 125 °C.
2 CATHODE passive Output of the shunt reference, adjustable from 1.24 V to 10 V per the recommended operating conditions.
3 ANODE passive Return terminal of the shunt reference, which must carry at least the minimum operating current IRMIN (73 µA max over -40 to 125 °C) and no more than 12 mA reverse current.
