# LM236H-5.0

**Texas Instruments** · Voltage Reference · TO-46-3

LM236H-5.0 from Texas Instruments, in a TO-46-3. 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 | passive | Adjustment terminal used to trim the 5.0V reference voltage (about ±1V) and its temperature coefficient, typically via a 10k potentiometer. |
| 2 | + | passive | Positive (cathode) terminal of the 5.0V shunt reference diode, operating from 600 μA to 10 mA with reverse current limited to 15 mA absolute maximum. |
| 3 | - | passive | Negative (anode) terminal of the 5.0V shunt reference diode, with forward current limited to 10 mA absolute maximum. |
