LM285LPRE3-1-2

Texas Instruments · Voltage Reference · TO-92

LM285LPRE3-1-2 from Texas Instruments, in a TO-92. 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 ANODE input Shunt reference current input terminal; accepts 0.01 mA to 20 mA reference current (maximum forward current 10 mA) to establish the reference voltage.
2 CATHODE power_in Reference ground and common terminal normally connected to ground; provides reference voltage of 1.223 to 1.247 V between anode and cathode with maximum 30 mA reverse current.
3 NC unconnected No internal connection.
