TPS26611DDFR from Texas Instruments, in a TSOT-23-8. 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	GND	power_in	Reference ground for all internal voltages; connect to GND of the ±Vs supply.
2	MODE	input	MODE selection pin for overload response; sets current limit to IOL, 2 × IOL, or 2 × IOL with extended IOL expiry time (GND, open, or 180 kΩ to GND), absolute max −0.3 to 5.5 V.
3	-Vs	power_in	Negative supply for dual supply configurations; connect to GND when used in a single supply configuration (recommended −20 V to 0 V).
4	IN	passive	Signal/power input, rated for −50 V to 50 V operating (±55 V absolute maximum).
5	OUT	passive	Signal/power output, rated for −50 V to 50 V operating (±55 V absolute maximum).
6	+Vs	power_in	Positive supply for powering the device, recommended 0 to 30 V (absolute max 32 V).
7	EN	input	Enable control on the TPS26611: pull EN low to turn off the device; it has an internal pullup and can be left floating to enable the device.
8	SGOOD	output	Signal good indicator that is low when the device is within normal operating condition and high on fault conditions; can drive an external LED, sourcing current from +Vs.
