LP6252B6F from LOWPOWER, in a SOT-23-6. 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. LP6252 turns on when VEN=high (>=1.4V) and turns off when VEN=0 (<=0.4V). Drives shutdown current below 1uA when low.
2	OUT	power_out	Boost converter voltage output pin. Connects to the output capacitor and load. Output range 2.5V to 5.4V, absolute max 6V to GND.
3	VIN	power_in	Voltage supply input pin. Operating range 2.5V to 5.5V, absolute max 6V to GND. Bypass with a 10uF low-ESR ceramic capacitor placed close to the pin.
4	SW	passive	Switching node. Connects to the external boost inductor (typically 1uH to 4.7uH; 2.2uH typical) between VIN and SW. Internal high-side PMOS and low-side NMOS switches drive this node at 1MHz.
5	GND	power_in	Ground reference pin. Return path for control and power stages.
6	FB	input	Regulation feedback input. Connect an external resistive voltage divider from OUT to FB to program the output voltage. Internal reference is 0.8V (784-816mV). VOUT = (R1/R2 + 1) x 0.8V. Feedback input current typically 50nA.
