LTP3328NXF4 from Linearin(先积集成), in a DFN1x1-4. 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 | OUT | power_out | Regulated output pin; bypass with a 1μF ceramic capacitor to ground (1μF to 2.2μF recommended, ESR 5mΩ to 100mΩ). |
| 2 | GND | power_in | Ground. |
| 3 | EN | input | Enable control input, active high (low threshold 0.4V, high threshold 1.4V); do not leave floating, tie to IN if unused. |
| 4 | IN | power_in | Supply input (2.5V to 6.0V); must be closely decoupled to GND with a 1μF or greater ceramic capacitor. |
| 5 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
