ZTP7106T from ZILLTEK, in a TSOT-23-5L. 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	Enable control input. Drive high (VENH >= 1.5V) to enable the converter; drive low (VENL <= 0.4V) to shut down the device (shutdown current < 1µA). EN input current is +/-1µA over 0V to Vin.
2	GND	power_in	Device ground return. Also the case position used for TSOT23-5 θJC measurement; connect to the ground plane with a low-impedance path.
3	SW	output	Power switch output. Common drain of the internal PMOS (UG) and NMOS (LG) power FETs; connect to the external inductor (2.2µH typ). Absolute max range -0.3V to Vin+0.3V; SW peak current 3A max; PMOS current limit typ 2A.
4	Vin	power_in	Main supply input, 2.5V to 5.5V. Bypass to GND with a 4.7µF ceramic (X5R/X7R) capacitor placed close to the pin. Absolute max 6V.
5	FB	input	Feedback input to the internal error amplifier. Regulates to VREF = 0.6V (0.588V/0.612V min/max); set Vout with a resistor divider from Vout to FB to GND: Vout = 0.6V x (1 + R1/R2). A small feed-forward capacitor (10-47pF, 22pF typical) in parallel with R1 speeds up transient response.
