TPS74501PCQWDRVRQ1 from Texas Instruments, in a WSON-6-EP(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. Adjustable output 0.55V to 5.5V, up to 500mA. Requires a ceramic output capacitor of at least 1µF (min derated 0.47µF) to GND for stability; place close to the pin. |
| 2 | FB | input | Feedback input to the control-loop error amplifier. Sets the LDO output voltage via an external resistor divider from OUT (VFB = 0.55V typical). FB pin bias current is ~10nA (0.1µA max). |
| 3 | GND | power_in | Device ground. Also electrically tied to the thermal pad. Provides return for the LDO and reference. |
| 4 | EN | input | Enable input. Drive above VEN(HI)=1.0V to enable the regulator; drive below VEN(LO)=0.3V to place the LDO in shutdown. Absolute max 6.5V; internal ~95kΩ pulldown; enable pin current ~10nA. |
| 5 | PG | output | Power-good status output. Available in open-drain or push-pull topologies (part-number dependent). Asserts high when VOUT rises above ~92% of nominal; deasserts when VOUT falls below ~90%. Open-drain versions require an external pull-up; tie to GND or leave floating if unused. |
| 6 | IN | power_in | Input supply pin. Operating range 1.5V to 6.0V (absolute max 6.5V). Requires at least 1µF ceramic input capacitor to GND; place close to the device. |
| PAD | Thermal Pad | passive | Thermal pad electrically connected internally to GND. Must be soldered to the PCB GND plane for improved thermal performance (RθJA = 80.3°C/W for DRV package). |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 710 faces against 50 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
