TPS745135PQWDRBRQ1 from Texas Instruments, in a SON-8-EP(3x3). 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 | OUT | power_out | Regulated output voltage pin providing up to 500 mA output current; requires 1 µF or larger ceramic capacitor to ground for stability. |
| 2 | NC | unconnected | No internal connection; ground this pin for better thermal performance. |
| 3 | NC | unconnected | No internal connection; ground this pin for better thermal performance. |
| 4 | GND | power_in | Ground reference pin; connect to system ground plane for improved thermal performance. |
| 5 | EN | input | Enable control input; drive EN greater than VEN(HI) to enable regulator or less than VEN(LO) to shutdown. |
| 6 | PG | output | Power-good open-drain output with 150-µs delay; pull-up resistor required for open-drain topology. |
| 7 | NC | unconnected | No internal connection; ground this pin for better thermal performance. |
| 8 | IN | power_in | Input power supply pin supporting 1.5 V to 6.0 V; requires 1 µF or larger ceramic capacitor to ground for transient response. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
