LD1086DTTR 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 | ADJ | input | Adjust/feedback pin that sets the output voltage via an external resistor divider (VO = VREF x (1 + R2/R1)); reference voltage 1.25 V typical, adjust pin current 40-120 uA (typ/max). |
| 2 | OUTPUT | passive | Regulated output voltage pin, guaranteed up to 1.5 A output current; internally connected to the package tab. |
| 3 | IN | passive | Unregulated DC input supply pin, absolute maximum 30 V, with typical dropout of 1.3 V at 1.5 A relative to the output. |
