LD8526UGL from Leadtrend Tech, in a SOT-26. 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	DRV	output	Gate driver output. Connects to the GATE of the external SR MOSFET directly or through a series resistor. Gate source/sink capability 0.5A / 3A; DRV output swing is 0V to VCC (max 14V).
2	GND	power_in	Device ground reference for VCC, DRV, DET and HVR.
3	VCC	power_in	Supply voltage pin. Recommended operating range 3V to 12V (absolute max 14V). Requires a minimum 2.2 uF bypass capacitor to GND. Can be self-supplied by the internal LDO from HVR.
4	DET	input	Synchronous rectification detection input. Senses the SR MOSFET drain voltage to determine turn-on/turn-off timing. Absolute max -1V to 200V; recommended series resistor RDET <= 600 ohm.
5	HVR	power_in	High-voltage linear regulator input. Feeds the internal LDO that generates the VCC self-supply. Absolute max -1V to 200V.
6	NC	unconnected	No connect. Leave floating or tie to a non-critical net per PCB layout.
