LM4132BMFX-3.0 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 floating. |
| 2 | GND | power_in | Ground pin for the device. |
| 3 | EN | input | Enable pin: EN between 65% of VIN and VIN enables the reference, EN between 0 V and 35% of VIN disables it, and EN must not be greater than VIN. |
| 4 | VIN | power_in | Input supply, which must be VREF + 400 mV to 5.5 V at 10 mA load (maximum input supply voltage 5.5 V). |
| 5 | VREF | power_out | Reference voltage output, capable of delivering up to 20 mA. |
