LP6222B6F from LOWPOWER, 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 | LX | passive | Switching node pin connected to the inductor and output diode; keep traces short and do not add capacitance (switch rated to 12V, 4.8A current limit). |
| 2 | GND | power_in | Ground. |
| 3 | FB | input | Regulation feedback input connected to an external resistive divider from the output to set the output voltage (0.6V typical feedback voltage). |
| 4 | EN | input | Regulator on/off control input: logic high (VEN>1.4V) turns on the regulator, logic low (VEN<0.4V) puts it into low current shutdown mode. |
| 5 | VIN | power_in | Power supply pin (2.5V to 5.5V supply range). |
| 6 | ISET | passive | Sets the LX peak current limit via a resistor to GND (10K to 96K gives 4.8A to 0.5A, IOCP=48000/R3); keep traces short and do not add capacitance. |
