**Texas Instruments** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SC-70-5

TPS71530QDCKRM3Q1 from Texas Instruments, in a SC-70-5. 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 connect pin that is not connected internally; connect to ground for best thermal performance or leave floating. |
| 2 | GND | power_in | Ground pin. |
| 3 | NC | unconnected | No connect pin that is not connected internally; connect to ground for best thermal performance or leave floating. |
| 4 | IN | power_in | Input supply pin, with the recommended input supply voltage range of 2.5 V to 24 V. |
| 5 | OUT | power_out | Regulator output; requires an effective output capacitance of at least 0.47 µF for stability. |
