LM334DT

STMicroelectronics · Current Source / Constant Current Source · SOIC-8

LM334DT from STMicroelectronics, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 ADJ input Current-set/adjust pin. An external R_set between ADJ and V- programs the output current per I_set = 67.7 mV / R_set at Tj = +25 °C. V_ADJ-to-V- is limited to 5 V max.
2 NC unconnected No internal connection.
3 NC unconnected No internal connection.
4 V+ power_in Positive supply / current-input terminal. The set current I_set flows into V+. Forward V+ to V- rating: 30 V (LM334), 40 V (LM134/LM234); reverse: 20 V. I_set ≤ 10 mA.
5 NC unconnected No internal connection.
6 V- power_in Negative supply / current-return terminal. R_set connects between ADJ and V-. Serves as the reference for the ADJ pin (V_ADJ to V- ≤ 5 V).
7 NC unconnected No internal connection.
8 NC unconnected No internal connection.
