Texas Instruments · Voltage Reference · SOT-23-5
LM4132BMF-3.3 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 that should be left floating. |
| 2 | GND | power_in | Ground reference for the device. |
| 3 | EN | input | Enable input: tie to VIN for normal operation or to GND for shutdown (about 3 µA); the datasheet gives enable as 65% of VIN to VIN and disable as 0 V to 35% of VIN, and VEN must not exceed VIN. |
| 4 | VIN | power_in | Input supply, which must be at least VREF + 400 mV (for ILOAD ≤ 10 mA) and no more than 5.5 V, with an input capacitor required close to the device. |
| 5 | VREF | power_out | Precision voltage reference output (3.3 V for this part), rated for up to 20 mA load current, with an output capacitor optional. |
