RT9080-28GJ5 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). Bypass with a ceramic capacitor to GND close to the pin.
2 GND power_in Ground reference for the regulator. Connect to the system ground plane with low impedance.
3 EN input Enable control input. Logic high (VIH >= 0.9V at VIN=5V) turns the regulator on; logic low (VIL <= 0.4V) shuts it down (shutdown IQ ~0.1 uA). Do not leave floating.
4 NC unconnected No internal connection on RT9080 variants (without SNS). May be left floating or tied to any potential within absolute maximum ratings. On the RT9080N variant this pin is the SNS output-voltage sense input.
5 VOUT power_out Regulated output of the LDO. Fixed 2.85V output for the -28 option, up to 600mA (VIN >= 2.3V). Requires >= 1 uF effective ceramic or tantalum output capacitor for stability.
