TLV74318PDBVR-HXY from HXY MOSFET, in a SOT-23-5L. 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; the datasheet gives a maximum input voltage of 6.5V and recommends a 10uF input capacitor between VIN and VSS for stable power input. |
| 2 | GND | power_in | Ground reference pin (referred to as VSS in the notes); the input and output capacitors should be placed as close to the IC as possible and the VIN-to-VSS wiring kept low resistance. |
| 3 | CE | input | Active-high ON/OFF control with EN logic high at 1.5V minimum and logic low at 0.4V maximum (VIN=5.0V); a series resistor must be under 10K, and driving it from VIN or VSS is recommended, with the output pulled to VSS in shutdown. |
| 4 | NC | unconnected | No connect pin; the datasheet does not assign it a function. |
| 5 | VOUT | power_out | Regulated output pin; an output capacitor of at least 10uF should be connected as close as possible to VOUT and VSS for phase compensation. |
