TPS77401DGK from Texas Instruments, in a VSSOP-8. 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 | FB/SENSE | input | Feedback input for the adjustable TPS77401, which must be connected to an external feedback resistor divider with the connection kept as short as possible. |
| 2 | PG | output | Open-drain, active-high power-good output that goes high-impedance when OUT reaches 82% of its regulated voltage and low-impedance when OUT falls below 82%, and it requires a pullup resistor. |
| 3 | EN | input | Enable input where a logic low enables the regulator and a logic high puts the device into shutdown. |
| 4 | GND | power_in | Regulator ground, which is the signal ground return for the output capacitor connected between OUT and GND. |
| 5 | IN | input | Input voltage pin, where an input capacitor is not usually required but a bypass of 0.047 µF or larger improves load transient response and noise rejection if the device is more than a few inches from the supply. |
| 6 | IN | input | Input voltage pin, connected in parallel with pin 5, where an input capacitor is not usually required but a bypass of 0.047 µF or larger improves load transient response and noise rejection if the device is more than a few inches from the supply. |
| 7 | OUT | output | Regulated output voltage pin that requires an output capacitor to GND of at least 1 µF with qualifying ESR, or at least 10 µF with a low-ESR capacitor, to keep the control loop stable. |
| 8 | OUT | output | Regulated output voltage pin, connected in parallel with pin 7, that requires an output capacitor to GND of at least 1 µF with qualifying ESR, or at least 10 µF with a low-ESR capacitor, to keep the control loop stable. |
