LM2576DP-5.0

HTC Korea TAEJIN Tech · DC-DC Converters · ESOP-8

LM2576DP-5.0 from HTC Korea TAEJIN Tech, in a ESOP-8. 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 switching regulator, which needs a suitable input bypass capacitor (Cin) to minimize voltage transients and supply switching currents.
2 VOUT output Emitter of the internal output switch with a typical saturation voltage VSAT of 1.5V; the PCB area on this pin should be kept to a minimum to reduce coupling to sensitive circuitry.
3 FEEDBACK input Senses the regulated output voltage to complete the feedback loop; on the adjustable version it is the direct input of the error amplifier, with R2/R1 connected externally to set the output voltage.
4 ON/OFF input Logic-level shutdown input: a voltage above the typical 1.4V threshold (up to +Vin) turns the regulator off, while a voltage below 1.4V or an open pin leaves it on.
5 N.C. unconnected No connect.
6 GND power_in Circuit ground pin; see the datasheet's printed circuit board layout information.
7 N.C. unconnected No connect.
8 N.C. unconnected No connect.
9 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
