LM2576S-5.0-MNS from Minos, 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; the datasheet gives a recommended supply range of 4.3 V to 40 V, with an absolute maximum rating of 45 V. |
| 2 | Output | power_out | Regulated output pin; the datasheet specifies 5 V, 12 V and adjustable output versions. |
| 3 | Gnd | power_in | Ground pin for the regulator. |
| 4 | Feedback | input | Feedback pin; in the adjustable (ADJ) version the datasheet specifies the output voltage as 1.23 V typical at this feedback node. |
| 5 | ON/OFF | input | ON/OFF control pin; the datasheet gives standby quiescent current Istby of 80 µA typical and 200 µA maximum at 25 °C with Pin5 = 5 V. |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
