LF25CDT-TR from STMicroelectronics, in a DPAK. 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 | INPUT | power_in | Unregulated DC input supply. Operating range up to 16 V (absolute maximum 18 V; regulator shuts down between 18 V and 40 V). Bypass with ~0.1 µF ceramic close to the pin. |
| 2 | GND | power_in | Device ground reference. Tied to the exposed tab of the DPAK package; the tab is electrically connected to GND and provides the primary thermal path to the PCB copper. |
| 3 | OUTPUT | power_out | Regulated 2.5 V output (±1.5% for the C grade, 2.475-2.525 V typ). Output current up to 500 mA with internal current and thermal limiting. Requires a 2.2 µF (ESR 0.1-10 Ω) capacitor to GND for loop stability. |
