VRH4501NTX from AnaSem, 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 | Voltage input; the datasheet's absolute maximum rating for VIN is -0.3 V to +7.0 V. |
| 2 | VSS | power_in | Power ground. |
| 3 | EN | input | Chip enable; pulling EN to VSS turns on the internal switch that discharges the charged ESR output capacitor so VOUT quickly returns to VSS. |
| 4 | NC | unconnected | Non-connection (leave open). |
| 5 | VOUT | power_out | Regulated output; the datasheet gives an output voltage range of VSS -0.3 V to VIN +0.3 V and a maximum output current of 500 mA. |
