Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | OUTPUT | power_out | Regulated +5 V output, up to 100 mA. A 0.1-uF capacitor to COMMON is recommended for stability and transient response. |+| 2 | COMMON | power_in | Common/ground reference for the regulator. Tie to system ground; internally connected to pins 3 and 6. |+| 3 | COMMON | power_in | Common/ground reference for the regulator. Tie to system ground; internally connected to pins 2 and 6. Also aids thermal dissipation via the PCB copper. |+| 4 | NC | unconnected | No internal connection. Leave floating or tie to COMMON as desired for PCB routing. |+| 5 | NC | unconnected | No internal connection. Leave floating or tie to COMMON as desired for PCB routing. |+| 6 | COMMON | power_in | Common/ground reference for the regulator. Tie to system ground; internally connected to pins 2 and 3. |+| 7 | COMMON | power_in | Common/ground reference for the regulator. Tie to system ground; internally connected to the other COMMON pins. |+| 8 | INPUT | power_in | Unregulated positive input. Recommended input voltage 7 V to 20 V for UA78L05AC (absolute max 30 V). A 0.33-uF bypass capacitor to COMMON is recommended when the regulator is located far from the power-supply filter. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-8 |+| Category | PMIC |+| Pins | 8 |++## Ordering variants++- `UA78L05ACDRD`+- `UA78L05ACDRDR`+- `UA78L05ACDRLP`+- `UA78L05ACDRLPE3`+- `UA78L05ACDRLPR`+- `UA78L05ACDRPK`++## CAD (KiCad official)++- Symbol: `UA78L05ACDR`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/ua78l05ac.pdf) (27 pp, sha256 `b5552b55c2be8616`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
