TPS745105PQWDRVRQ1 from Texas Instruments, in a WSON-6-EP(2x2). 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 that requires a capacitor from OUT to ground for stability, using the recommended value or larger ceramic capacitor (COUT range 1 µF to 220 µF, minimum derated 0.47 µF) placed as close to the device as possible. |
| 2 | NC | unconnected | No internal connection on the fixed-voltage DRV package; the datasheet recommends grounding this pin for better thermal performance. |
| 3 | GND | power_in | Ground pin. |
| 4 | EN | input | Enable input: drive above VEN(HI) to turn on the regulator and below VEN(LO) to place the LDO in shutdown, with VEN rated 0 V to 6.0 V. |
| 5 | PG | output | Power-good output; this part has no push-pull suffix so it is an open-drain output that requires a pull-up resistor, and if power-good is unused it should be grounded or left floating (VPG rated 0 V to 6.0 V, IPG limited to ±10 mA). |
| 6 | IN | power_in | Input supply pin with a rated input voltage of 1.5 V to 6.0 V; use the recommended value (1 µF minimum) or larger ceramic capacitor from IN to ground, placed as close to the device as possible. |
| 7 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
