LM2575HVSX-ADJ from Texas Instruments, in a TO-263-5. 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 | Vin | power_in | Power supply input voltage, operating range 40V to 60V for LM2575HV with maximum absolute rating of 63V. |
| 2 | Vout | power_out | Regulated output voltage adjustable 1.23V to 57V for LM2575HV-ADJ with 1A maximum output current and ±4% line and load regulation. |
| 3 | GND | power_in | Power supply ground and signal common return requiring low-impedance connection to ground plane for stable regulation. |
| 4 | Feedback | input | Output voltage feedback input requiring 1.23V nominal reference voltage with feedback bias current of 50nA to 500nA. |
| 5 | On/Off | input | TTL shutdown control input requiring minimum 2.2V logic high to disable or maximum 1.0V logic low to enable regulator, with 50μA standby current. |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
