LM4132AMFX-3.3 from Texas Instruments, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | N/C | unconnected | No connect pin shall be left floating. |
| 2 | GND | power_in | Ground reference provides return path for all circuit currents. |
| 3 | EN | input | Enable input pin accepts voltage from 0V to VIN; device enables when EN ≥ 65% of VIN and disables when EN ≤ 35% of VIN. |
| 4 | VIN | power_in | Input supply voltage shall be between VREF + 400mV and 5.5V, which is 3.7V to 5.5V for the 3.3V output variant. |
| 5 | VREF | power_out | Precision voltage reference output provides 3.3V nominal with 0.05% initial accuracy, 60µA typical quiescent current, and 20mA maximum load current capability. |
