LM385BD-2.5R2G

onsemi · Voltage References · SOIC-8

LM385BD-2.5R2G from onsemi, 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 a convenient node.
2 NC unconnected No internal connection.
3 NC unconnected No internal connection.
4 Anode passive Anode of the reference diode. Typically returned to the circuit ground/return. The device regulates V(BR)R = 2.500 V (min 2.462 / max 2.538 V at 25 °C) from Cathode to Anode when biased with 20 µA to 20 mA of reverse current.
5 NC unconnected No internal connection.
6 NC unconnected No internal connection.
7 NC unconnected No internal connection.
8 Cathode passive Cathode of the reference diode. Positive terminal when the device is reverse-biased. Held at ~2.500 V above the Anode over the operating current range (IRmin ≈ 13 µA typ, up to 20 mA).
