LP3992-28B5F from LOWPOWER, 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 | VIN | power_in | Power input voltage, with a recommended supply range of 2.5V to 5.5V and an absolute maximum supply input of 6.5V. |
| 2 | GND | power_in | Ground reference pin for the regulator. |
| 3 | EN | input | Active-high chip enable: the LDO turns on when EN is above 1.4V (VIH) and shuts down when EN is below 0.4V (VIL), with the EN input limited to 0V to VIN+0.3V. |
| 4 | NC | unconnected | No connection; this pin is not connected internally. |
| 5 | VOUT | power_out | Regulated output voltage, supplying up to 300mA of output current. |
