TPS7A2550DRVR 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; requires output capacitor (1-100 μF) from OUT to GND for stability with low equivalent series resistance. |
| 2 | NC | unconnected | No internal connection for fixed-voltage version only; may float or tie to GND for improved thermal performance. |
| 3 | PG | tri_state | Power-good open-collector output; releases to high-impedance when VOUT > VIT(PG,RISING) (96.5% nominal), driven low when VOUT < VIT(PG,FALLING) (90% nominal). |
| 4 | EN | input | Active-high enable input; EN > VEN(HI) (0.9 V) enables output, EN < VEN(LOW) (0.4 V) enters shutdown; do not leave floating, connect to IN if unused. |
| 5 | GND | power_in | Ground reference pin providing return path for all device currents. |
| 6 | IN | power_in | Unregulated input supply pin, 2.4 V to 18 V; requires input capacitor (≥1 μF) from IN to GND for transient response and ripple rejection. |
| 7 | Thermal Pad | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
