LM2575HVR-5.0 from HTC Korea TAEJIN Tech, in a TO-263-5L. 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 | Input supply pin with an operating supply voltage up to 60 V and an absolute maximum of 63 V. |
| 2 | VOUT | power_out | Regulated output pin; the steady-state output voltage to ground is rated down to -0.75 V. |
| 3 | GND | power_in | Ground reference pin that must be connected with short, single-point or ground-plane return paths for best regulation. |
| 4 | FB/ADJ | input | Feedback pin that senses the output; for the adjustable version, VOUT = VREF(1+R2/R1) with VREF = 1.23 V. |
| 5 | ON/OFF | input | TTL-compatible shutdown input that switches the regulator off when driven high, giving a typical standby current of 50 uA. |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
