LM2575GR-5.0

HTC Korea TAEJIN Tech · DC-DC Converters · TO-263-5

LM2575GR-5.0 from HTC Korea TAEJIN Tech, 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 Positive input supply for the step-down regulator; a suitable input bypass capacitor (Cin) must be present to minimize voltage transients and supply the switching currents.
2 Output output Emitter of the internal output switch, with a typical saturation voltage Vsat of 1.5 V; keep the PCB area on this pin minimal to reduce coupling to sensitive circuitry.
3 Ground power_in Circuit ground pin; see the datasheet's printed circuit board layout guidance.
4 Feedback input Senses the regulated output voltage to close the feedback loop; on the adjustable version it is the direct input to the error amplifier and R2/R1 are connected externally to program the output voltage.
5 ON/OFF input TTL-compatible shutdown input with a typical threshold of 1.4 V: applying a voltage above this (up to +Vin) shuts the regulator off, while a voltage below 1.4 V or an open pin leaves it on.
6 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
