PAM2804AAB010 from MSKSEMI, in a SOT-23-5. 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	EN	input	Chip Enable pin. Drive above 1.5V to turn on; drive below 0.4V to turn off. Do not leave floating.
2	GND	power_in	Ground reference pin for the device.
3	LX	output	Power Switch Output. Switch node connection to the external inductor. Rated up to 6.5V absolute max; peak current limit 1.5A.
4	VIN	power_in	Power Supply Input, 2.5V to 5.5V operating range (6.5V abs max). Must be closely decoupled to GND with a 4.7µF or greater ceramic capacitor.
5	FB	input	Feedback pin, regulated at 0.1V (typ). A sense resistor between FB and GND programs the LED current per ILED = VFB / R1.
