LM2575S-5.0RG

HANSCHIP semiconductor · DC-DC Converters · TO-263-5

LM2575S-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 pin, rated up to 40 V for LM2575 (55 V for LM2575HV) maximum.
2 Output output Switching regulator output (internal power switch output) that connects to the inductor and catch diode.
3 Ground power_in Ground pin; the package tab is also connected to GND.
4 Feedback input Feedback sense input to the regulator that senses the output voltage; the datasheet's adjustable version uses a 1.23 V reference.
5 ON/OFF input Active-low shutdown input (TTL-compatible) that puts the device in standby mode (typical 50 µA); the input range is -0.3 V to VIN.
6 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
