ETA5052V0S2G

etasolution · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-6

ETA5052V0S2G from etasolution, in a SOT-23-6. 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; the input voltage range is 2.7 V to 5.5 V, and VIN is rated to a 6 V absolute maximum.
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 0.5 V max and logic-high at 1.2 V min for 2.7 V ≤ VIN ≤ 5.5 V; it can be connected to VIN if not used.
4 REFBP passive Reference voltage bypass pin; bypass it to GND with an external capacitor to improve high-frequency PSRR, and it is rated to 6 V absolute maximum.
5 FB input Feedback pin for setting the output voltage through an external resistor divider, with a feedback voltage of 1.178 V to 1.222 V and a 1 µA pin current at VFB = 1.8 V.
6 VOUT power_out Output of the regulator, rated for 300 mA continuous output current with an internal current limit of 350 mA to 600 mA.
