LD1085D2T-R from STMicroelectronics, in a D2PAK. 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 | ADJ/GND | passive | Adjust pin on the adjustable version (reference voltage 1.25 V, adjust pin current typ. 55 µA, max 120 µA) and ground on the fixed-voltage versions. |
| 2 | OUTPUT | power_out | Regulated output for up to 3 A guaranteed output current, with a minimum 10 µF capacitor needed for stability. |
| 3 | INPUT | power_in | Unregulated input voltage, absolute maximum 30 V DC, with typical dropout of 1.3 V at 3 A. |
