SPX3819M5-L-2-5 from MaxLinear, 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 | Supply input; operating input range is 2.5V to 16V (absolute maximum -20V to +20V). |
| 2 | GND | power_in | Ground. |
| 3 | EN | input | Enable input, CMOS compatible: logic high (≥2V) enables, logic low (≤0.4V) or open shuts down the regulator; range 0.0V to VIN. |
| 4 | BYP | passive | Fixed-version internal reference bypass pin; connect 10nF to ground to reduce output noise (may be left unconnected if noise is not a concern). |
| 5 | VOUT | power_out | Regulator output (fixed 2.5V for the -2-5 option, up to 500mA); requires an output capacitor for stability. |
