TPS79501DRBR from Texas Instruments, in a WSON-8-EP(3x3). 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 | IN | power_in | Power supply input, 2.7V to 6.0V nominal for new chip variant. |
| 2 | IN | power_in | Power supply input in parallel with pin 1 to reduce impedance. |
| 3 | OUT | power_out | Regulated output voltage; requires minimum 1µF bypass capacitor to ground for stability. |
| 4 | OUT | power_out | Regulated output voltage in parallel with pin 3. |
| 5 | FB | input | Feedback input for adjustable output voltage configuration with internal reference voltage 1.225V nominal. |
| 6 | GND | power_in | Ground reference for the regulator and bypass capacitors. |
| 7 | N/C | unconnected | No internal connection. |
| 8 | EN | input | Enable input; drive high to enable regulator, low for shutdown mode. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
