Texas Instruments · DC-DC Converters · SOT-23-5
LM2831ZMF 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 | SW | output | Output switch pin for step-down converter; connect to the inductor and catch diode. |
| 2 | GND | power_in | Signal and power ground pin; place the bottom resistor of the feedback network as close as possible to this pin. |
| 3 | FB | input | Feedback pin; connect to external resistor divider to set output voltage from 0.6 V to 4.5 V. |
| 4 | EN | input | Enable control input; logic high enables operation; do not allow this pin to float or be greater than VIN + 0.3 V. |
| 5 | VIN | power_in | Input supply voltage; operate from 3 V to 5.5 V. |
