REG71055DDCR from Texas Instruments, in a TSOT-23-6. 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 | Vout | output | Regulated output supply pin with nominal 5.5 V output; connect output capacitor (2.2 μF minimum), supports load current up to 30 mA from 3.25 V to 5.5 V input. |
| 2 | GND | power_in | Ground reference node; connection point for return currents from input and output, and pump capacitor midpoint. |
| 3 | Enable | input | Hardware enable/disable control pin; logic high input (1.3 V to VIN) enables converter, logic low input (-0.2 V to 0.4 V) activates shutdown mode with <1 μA quiescent current. |
| 4 | Cpump- | passive | Flying capacitor negative terminal; connect 0.22 μF ceramic surface-mount capacitor with X7R or X5R dielectric. |
| 5 | Vin | power_in | Unregulated input supply pin accepting 3 V to 5.5 V input voltage; connect 2.2 μF ceramic surface-mount bypass capacitor. |
| 6 | Cpump+ | passive | Flying capacitor positive terminal; connect 0.22 μF ceramic surface-mount capacitor with X7R or X5R dielectric. |
