ETA5041V0NS2F

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

ETA5041V0NS2F 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 (input range 3V to 45V, absolute max 48V); bypass with a 1μF ceramic capacitor to GND.
2 GND power_in Ground.
3 EN input Enable pin; drive high (above 1.2V rising threshold) to enable the IC and low (below 0.4V falling threshold) to disable, default high when floating.
4 FB/NC input Feedback pin for output voltage configuration on the adjustable version (Vout = (R1+R2)/R2 x 1V, FB voltage 1V); this part ETA5041V0NS2F is the adjustable version so FB is used.
5 OUT power_out Output voltage pin (up to 300mA); bypass with a 1μF ceramic capacitor to GND.
