LM217D2T-TR 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 | ADJUST | passive | Adjustment terminal that sets the output voltage via the R1/R2 divider, with IADJ of 100 µA max and the 1.25 V reference (1.2 to 1.3 V) held between OUTPUT and ADJUST. |
| 2 | OUTPUT | power_out | Regulated output (1.2 to 37 V, over 1.5 A, internally current limited) that is also connected to the D²PAK tab and needs a minimum load current of 3.5 mA typ (10 mA max for LM317). |
| 3 | INPUT | power_in | Unregulated input; the input-to-output differential voltage must not exceed 40 V. |
