LMS1587CT-ADJ from Texas Instruments, in a TO-220. 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 LMS1587CT-ADJ, where the 1.25V VREF appears between OUTPUT and ADJ and sets VOUT through resistors R1 and R2 (IADJ 55 µA typical, 120 µA max); it is the ground pin on fixed versions. |
| 2 | OUTPUT | power_out | Regulated output (3A rated for the LMS1587), which needs an output capacitor of at least 10 µF for stability and has a 1.2V typical dropout and a 3.1A minimum current limit. |
| 3 | INPUT | power_in | Unregulated supply input, where the maximum input-to-output voltage is 13V and a 10 µF input capacitor is shown in the typical application. |
