TPS74501PQWDRVRQ1 from Texas Instruments, in a WSON-6(2x2). Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT | power_out | Regulated output voltage pin. Requires a ≥1 µF ceramic output capacitor (min derated 0.47 µF) to GND close to the pin for stability. Sources up to 500 mA continuously. |
| 2 | FB | input | Feedback input to the internal error amplifier for the adjustable variant. Connect the top of the external resistor divider to OUT and the tap to FB to program VOUT (VFB = 0.55 V typ). Absolute max: -0.3 V to 2.0 V. |
| 3 | GND | power_in | Device ground. Also connected to the exposed thermal pad; tie both to the ground plane for best thermal and noise performance. |
| 4 | EN | input | Enable input. Drive above VEN(HI) to turn on the regulator; drive below VEN(LO) for shutdown (ISHDN ≈ 0.1 µA). Input range 0 V to 6.0 V; toggle frequency up to 10 kHz. |
| 5 | PG | output | Power-good status output. Configurable as open-drain (needs external pull-up, ≤6.0 V) or push-pull. Asserts high when VOUT is within regulation; float or tie low if unused. IPG max ±10 mA. |
| 6 | IN | power_in | Supply input, 1.5 V to 6.0 V operating (absolute max 6.5 V). Place a ≥1 µF ceramic input capacitor close to the pin for best transient response. |
| PAD | Thermal Pad | passive | Exposed die-attach pad, electrically tied to GND. Solder to a GND copper pour to achieve the datasheet 80.3 °C/W RθJA for the DRV (WSON-6) package. |
