ETA5050V28S2F

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

ETA5050V28S2F from etasolution, 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 VIN power_in Input supply pin; input voltage range is 1.6V to 6.0V (absolute maximum -0.3V to 6V).
2 GND power_in Ground pin.
3 EN input Enable pin: drive high (at least 1.4V) to enable the IC and low (at most 0.4V) to disable it, and it can be connected to IN if not used.
4 NC unconnected Not connected.
5 VOUT power_out Regulator output pin, with 500mA continuous output current and a recommended 1uF output capacitor.
