LDK120M32R from STMicroelectronics, in a SOT-23-5L. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IN | power_in | Input voltage supply; operating range 1.9 to 5.5 V DC |
| 2 | GND | power_in | Common ground reference |
| 3 | EN | input | Enable logic input; Low = shutdown mode, High = active mode |
| 4 | BYP | passive | Bypass capacitor connection for noise reduction on fixed version; optional, must be left floating with no routing if not used |
| 5 | OUT | power_out | Output voltage 3.2 V nominal; delivers up to 200 mA maximum output current |
