ETA5050V30S2F

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

ETA5050V30S2F 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, rated for 1.6V to 6.0V operation with absolute maximum voltage of -0.3V to 6V, and minimum VIN of 2.0V or VOUT + VDROPOUT, whichever is greater.
2 GND power_in Ground pin for the regulator.
3 EN input Enable pin: drive high to enable the IC and low to disable it, with logic low at most 0.4V and logic high at least 1.4V for 1.8V ≤ VIN ≤ 6V, and it can be connected to VIN if not used.
4 NC unconnected Not connected.
5 VOUT power_out Output of the regulator, rated up to 500mA continuous current when not limited by package heat dissipation and dropout, with the 3.0V variant (ETA5050V30S2F) providing a 3.0V nominal output.
