HANSCHIP semiconductor · DC-DC Converters · TO-263-5
LM2576S-5.0RG from HANSCHIP semiconductor, 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, maximum 40 V for LM2576 (55 V for LM2576HV). |
| 2 | Output | output | Switching regulator output; output voltage to ground (steady state) must not go below -1 V. |
| 3 | Ground | power_in | Ground pin; the package tab is also ground. |
| 4 | Feedback | input | Feedback sense input; for the fixed 5.0 V version it connects to the output. |
| 5 | ON/OFF | input | Active-low shutdown input (low = on), TTL-compatible with a range of -0.3 V to VIN, giving about 50 uA typical standby current when high. |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
