LM2841XMKX-ADJL from Texas Instruments, in a SOT-23-6. 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 | CB | input | SW FET gate bias voltage; connect the CBOOT capacitor between CB and SW, with CB voltage above SW limited to 7 V absolute maximum. |
| 2 | GND | power_in | Ground connection. |
| 3 | FB | input | Feedback pin set by VOUT = VFB(1 + R1/R2) with VFB of 0.765 V; resistors must be 100 Ω to 10 kΩ to avoid input bias errors, and FB is rated -0.3 V to 5 V. |
| 4 | SHDN | input | Logic-level shutdown input that disables the device when pulled to GND and enables it when pulled high; it must not float and should be tied to VIN if unused, with absolute maximum of -0.3 V to VIN + 0.3 V and below 45 V. |
| 5 | VIN | power_in | Power input with a 4.5 V to 42 V normal operating range and 45 V absolute maximum. |
| 6 | SW | output | Power FET output connected to the inductor, catch diode and CBOOT capacitor, with SW voltage rated up to 42 V (absolute maximum 45 V). |
