TPS2553DBVR from Texas Instruments, 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	IN	power_in	Input supply voltage (2.5 V to 6.5 V). Connect a 0.1 µF or greater ceramic bypass capacitor from IN to GND as close to the IC as possible.
2	GND	power_in	Ground reference for the device. For WSON package, connect externally to the PowerPAD; on SOT-23 there is no thermal pad.
3	EN	input	Enable input; logic HIGH turns on the power switch (TPS2553 is active-high; the TPS2552 variant uses active-low EN̄ on the same pin).
4	FAULT	output	Active-low open-drain fault output; asserted during overcurrent, overtemperature, or reverse-voltage conditions. Requires an external pull-up (e.g., 100 kΩ). Continuous sink current rated up to 25 mA.
5	ILIM	output	Current-limit programming pin. External resistor to GND sets current-limit threshold; recommended 15 kΩ ≤ R_ILIM ≤ 232 kΩ. ILIM source current is limited to 1 mA absolute maximum.
6	OUT	power_out	Power-switch output. Current-limited high-side switched supply to the downstream load (up to 1.5 A continuous, 1.7 A typical current-limit ceiling).
