ETA5041V330DS2F

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

ETA5041V330DS2F 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 IN power_in Supply voltage pin with a 3 V to 45 V operating input range (absolute maximum IN to GND is 48 V); bypass with a 1 µF ceramic capacitor to GND.
2 GND power_in Ground reference pin for the regulator.
3 EN input Enable pin: drive high to enable and low to disable the IC; it defaults high when floating, with a logic high threshold of 1.2 V (rising) and a logic low threshold of 0.4 V (falling).
4 FB/NC unconnected Not connected on the fixed-voltage version, so this 3.3 V part leaves the pin unconnected; the FB feedback input for output voltage setting applies only to the adjustable version.
5 OUT power_out Regulated output voltage pin (300 mA output current capability); bypass with a 1 µF ceramic capacitor to GND.
