TPS74533PQWDRVRQ1 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 3.3V output voltage pin; requires 0.47µF to 220µF capacitor to GND for stability. |
| 2 | NC | unconnected | No internal connection; ground this pin for improved thermal performance. |
| 3 | GND | power_in | Ground reference pin. |
| 4 | EN | input | Enable input; drive above VEN(HI)=1.0V minimum to turn on regulator, below VEN(LO)=0.3V maximum to shutdown. |
| 5 | PG | tri_state | Open-drain power-good output; indicates output voltage regulation status with PGLTH=86% to PGHTH=92% VOUT hysteresis range. |
| 6 | IN | power_in | Power supply input pin accepting 1.5V to 6.0V nominal range; place ≥1µF input capacitor close to this pin. |
| 7 | Thermal Pad | power_in | Thermal pad electrically connected to GND; connect to GND plane with vias for improved thermal performance. |
