LM2575S-ADJ from Slkor SLKORMICRO Elec, 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 | Unregulated input supply pin; the datasheet rates VIN at 45 V absolute maximum, with a 4V to 40V operating input range. |
| 2 | OUTPUT | power_out | Switching output of the internal power transistor that drives the external inductor and catch diode; the steady-state output voltage to common must not go below -1 V. |
| 3 | COMMON | power_in | Ground (common) pin; the package tab is also connected to COMMON. |
| 4 | FEEDBACK | input | Feedback sense input to the error amplifier; the ADJ version regulates this pin to 1.23 V typical (VFB 1.217 to 1.243 V) through an external R1/R2 divider. |
| 5 | ON/OFF | input | Active-low enable input that shuts the regulator down when high; the datasheet gives -0.3 V to VIN as the pin voltage range, with logic low max 1.0 V and logic high min 2.2 V. |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
