LP6483SPF from LOWPOWER, in a ESOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	NC	unconnected	No connect. Pin is not internally bonded; may be left floating or tied to a static net for PCB routing convenience.
2	VIN	power_in	Supply input. Operating range 4.5V to 30V (36V absolute max, 32V typical OVP lockout). Bypass locally with 10uF x2 ceramic capacitors to GND.
3	SW	output	Switch node. Connects to the drains of the internal high-side and low-side power MOSFETs. Tie to the external inductor (typ. 10uH) to form the buck output stage.
4	GND	power_in	Ground return. Must be tied to the exposed pad (pin 9) and connected to the PCB ground plane for both current return and heat sinking.
5	FB	input	Feedback input to the internal error amplifier. Connect to the mid-point of the external R1/R2 output resistor divider; regulates to Vref = 0.6V (0.588-0.612V). VOUT = 0.6V x (1 + R1/R2). Absolute max -0.3V to 6V.
6	NC	unconnected	No connect. Pin is not internally bonded; may be left floating or tied to a static net for PCB routing convenience.
7	EN	input	Enable control input. Drive above 2.5V (VEN(H)) to turn the converter on; drive below 0.4V (VEN(L) max 1V) to shut it down (I_SHDN < 0.1uA typ, 10uA max). Absolute max 36V; not internally pulled up.
8	NC	unconnected	No connect. Pin is not internally bonded; may be left floating or tied to a static net for PCB routing convenience.
9	GND	power_in	Exposed thermal pad on the underside of the ESOP-8. Must be soldered to the PCB ground plane; ties to pin 4 GND and provides the primary heat path (theta_JA = 50 C/W).
