LM2735YMY from Texas Instruments, in a MSOP-8-EP. 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 | NC | unconnected | No-connect pin on the MSOP-PowerPAD package; it is not used by the regulator. |
| 2 | PGND | power_in | Power ground pin; place PGND and the output capacitor ground close together. |
| 3 | VIN | power_in | Supply voltage for the power stage and input supply; recommended operating range is 2.7 V to 5.5 V, with absolute maximum of 7 V. |
| 4 | EN | input | Shutdown control input where logic high enables operation; do not let this pin float or exceed VIN + 0.3 V. |
| 5 | FB | input | Feedback pin; connect to an external resistor divider to set the output voltage (absolute maximum 3 V). |
| 6 | AGND | power_in | Signal ground pin; place the bottom resistor of the feedback network as close as possible to this pin and to pin 5 (FB). |
| 7 | SW | output | Output switch pin; connect to the inductor and output diode (absolute maximum 26.5 V). |
| 8 | NC | unconnected | No-connect pin on the MSOP-PowerPAD package; it is not used by the regulator. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
