# ETA5071V330DS2F

**ETA(钰泰)** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

ETA5071V330DS2F from ETA(钰泰), 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; input voltage range is 1.8V to 6.5V, and minimum VIN is 1.8V or VOUT + VDROPOUT, whichever is greater. |
| 2 | GND | power_in | Ground pin. |
| 3 | EN | input | Enable pin: drive high to enable the IC and drive low to disable it; EN can be connected to VIN if not used (logic low max 0.4V, logic high min 1.2V for 1.8V ≤ VIN ≤ 5.5V). |
| 4 | NC | unconnected | Not connected. |
| 5 | VOUT | power_out | Output of the regulator, delivering up to 300mA output current. |
