LM336MX-2.5

Texas Instruments LM336MX 2 5 NOPB · Voltage Reference · SOIC-8

LM336MX-2.5 from Texas Instruments LM336MX 2 5 NOPB, 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 NC unconnected No internal connection. Leave floating or tie to any convenient net.
2 - passive Anode (negative) terminal of the 2.5V shunt reference. Typically tied to ground/return; the reference sinks 400 µA to 10 mA of shunt current through this pin.
3 NC unconnected No internal connection.
4 NC unconnected No internal connection.
5 ADJ input Adjustment terminal. Allows trimming of the 2.5V reference voltage (nominal 2.490V trim point) and minimization of temperature coefficient via an external 10kΩ pot and compensating signal diodes. May be left open for untrimmed operation.
6 NC unconnected No internal connection.
7 NC unconnected No internal connection.
8 + passive Cathode (positive) terminal of the 2.5V shunt reference. Biased through an external series resistor from the supply; regulates to +2.5V above the '-' terminal with reverse current 400 µA to 10 mA (15 mA absolute max).
