REG711EA-5 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 | NC | unconnected | No internal connection; the datasheet gives no function for this pin. |
| 2 | Enable | input | Shutdown control input: logic high needs at least 1.3 V (up to VIN), logic low is 0.4 V max, and input current is 100 nA max each state; shutdown cuts supply current to 2 µA max. |
| 3 | VIN | power_in | Input supply for the 5.0 V version, 2.7 V to 5.5 V guaranteed startup (absolute maximum supply is 5.5 V). |
| 4 | GND | power_in | Ground reference for the regulator; the datasheet's layout places the star-ground center at pin 5. |
| 5 | PGND | power_in | Power ground for the pump and output currents, and the center of the recommended star-ground layout. |
| 6 | CPUMP- | passive | Negative terminal of the 0.22 µF charge-pump capacitor (CPUMP), a surface-mount X7R or X5R ceramic recommended. |
| 7 | CPUMP+ | passive | Positive terminal of the 0.22 µF charge-pump capacitor (CPUMP), a surface-mount X7R or X5R ceramic recommended. |
| 8 | VOUT | power_out | Regulated output, 5.0 V for this version, rated 50 mA nominal with 80 mA short-circuit current and about 40 mVp-p ripple at 50 mA. |
