LM336BZ-2.5 from Texas Instruments, in a TO-92-3. 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 | ADJ | input | Adjust terminal; connect to an external resistive divider or potentiometer (2 kΩ-20 kΩ) to trim the reference voltage and minimize temperature coefficient; does not affect temperature coefficient when only breakdown voltage is adjusted. |
| 2 | K | power_out | Cathode; 2.5 V shunt reference output, 2.440 V min / 2.490 V typ / 2.540 V max (LM336B-2.5, IR = 1 mA, TA = 25 °C); operating reverse current 400 µA to 10 mA, dynamic impedance 0.2 Ω typ / 1 Ω max. |
| 3 | A | power_in | Anode; low-side terminal of the shunt regulator, referenced to ground; maximum forward current 10 mA, maximum reverse current 15 mA. |
