ETA5053V330DF1E

etasolution · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · DFN-4-EP(1x1)

ETA5053V330DF1E from etasolution, in a DFN-4-EP(1x1). 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 VOUT power_out Output of the regulator; the fixed 3.3 V output (for this 3.3V discharge part) supplies up to 300 mA continuous output current.
2 GND power_in Ground pin.
3 EN input Enable pin: drive high to enable the IC and low to disable it; logic high is at least 1.4 V and logic low is at most 0.4 V for 1.8 V ≤ VIN ≤ 6 V, and EN can be tied to VIN if unused.
4 VIN power_in Input supply pin; the input voltage range is 1.6 V to 6.0 V, and the minimum VIN is 1.6 V or VOUT + VDROPOUT, whichever is greater.
5 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
