ETA5055V280DS2F

ETA(钰泰) · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

ETA5055V280DS2F from ETA(钰泰), in a SOT-23-5. 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 IN power_in Input supply pin; the electrical characteristics specify an input voltage range of 1.8 V to 5.5 V.
2 GND power_in Ground pin.
3 EN input Enable pin: drive high to enable the IC and drive low to disable it, with logic-low 0.4 V and logic-high 0.9 V thresholds listed for 1.8 V ≤ VIN ≤ 5.5 V.
4 NC unconnected Not connected.
5 OUT power_out Regulated output of the LDO, rated for a continuous output current of 500 mA.
