LM2576S-5.0RG

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).
