LMS1587CT-3.3 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 | GND | power_in | Ground reference for the fixed 3.3V LMS1587-3.3 (ADJ/GND pin, which is the adjust pin only on the adjustable version), with typical quiescent current of 7.0 mA and 13.0 mA max at VIN = 5V. |
| 2 | OUTPUT | power_out | Regulated 3.3V output (3.235V to 3.365V over 0 to 3A load, 4.75V ≤ VIN ≤ 7V), with current limit of 3.1A min and 4.3A max, which also connects to the metal tab and needs a 10 µF capacitor for stability. |
| 3 | INPUT | power_in | Unregulated supply input requiring at least 4.75V for the 3.3V output (up to 7V in the regulation specs), with dropout of about 1.15V typical at 3A and a 13V absolute maximum input-to-output differential. |
