RT9080-25GJ5 from Richtek Tech, in a TSOT-23-5. 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 VIN power_in Supply voltage input. Operating range 1.2V to 5.5V; absolute max −0.3V to 6.5V referenced to GND.
2 GND power_in Ground reference for the regulator.
3 EN input Enable control input. Logic-high (VIH ≥ 0.9V at VIN = 5V) turns the regulator on; logic-low (VIL ≤ 0.4V) puts the device into shutdown with typical 0.1µA GND current. Absolute max −0.3V to 6.5V.
4 NC unconnected No internal connection. This RT9080 (no-SNS) variant leaves pin 4 unconnected; the SNS pin exists only on the RT9080N option.
5 VOUT power_out Regulated output. Fixed 2.5V (-25 option code); delivers up to 600mA when VIN ≥ VOUT + VDROP. Requires ≥1µF effective ceramic or tantalum output capacitor for stability.
