Texas Instruments · Voltage Reference · SOT-23-5
LM4132BMFX-1.8 from Texas Instruments, in a SOT-23-5. 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 | N/C | unconnected | No-connect pin; leave it floating. |
| 2 | GND | power_in | Ground reference for the device. |
| 3 | EN | input | Enable input: drive it between 65% of VIN and VIN to enable the device, or between 0 V and 35% of VIN to put it in shutdown; VEN must not exceed VIN or the device does not operate correctly. |
| 4 | VIN | power_in | Input supply, which must satisfy VIN > VREF + 400 mV at ILOAD ≤ 10 mA and stay within the 5.5 V maximum input supply voltage; a CIN input capacitor is required close to this pin. |
| 5 | VREF | power_out | Precision reference output that sources up to 20 mA; an output capacitor is optional and must satisfy CIN ≥ COUT if used. |
