LD2985BM25R from STMicroelectronics, 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 | IN | power_in | Input port; DC input voltage range 2.5 V to 16 V for device operation |
| 2 | GND | power_in | Ground pin; reference potential and return path for all circuits |
| 3 | INHIBIT | input | Control switch ON/OFF; disable device when connected to GND or positive voltage less than 0.18 V, TTL-compatible with logic low threshold 0.15 V and logic high threshold 2 V |
| 4 | Bypass | passive | Bypass pin; connect 10 nF external capacitor to GND to improve thermal noise performance to 30 µVrms |
| 5 | OUT | power_out | Output port; regulated 2.5 V output voltage at output current range 1 to 150 mA with dropout voltage 280 mV at 150 mA load |
