LM2575SX-5.0-JSM from JSMSEMI, 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; absolute maximum input voltage is 45 V and the wide input range is 4 V to 40 V. |
| 2 | OUTPUT | output | Switching regulator output (emitter of internal power transistor) driving the inductor and catch diode; steady-state output voltage to common is limited to -1 V minimum. |
| 3 | COMMON | power_in | Common (ground) pin of the regulator; the package tab is also connected to COMMON. |
| 4 | FEEDBACK | input | Feedback sense input to the error amplifier; connected to the output for fixed 5.0 V option (1.23 V reference for adjustable version). |
| 5 | ON/OFF | input | Active-low shutdown/enable control input; limited to -0.3 V to VIN, logic low max 1.0 V (on) and logic high min 2.2 V (off). |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
