# D1117-5.0

**Silicore(芯谷)** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223

D1117-5.0 from Silicore(芯谷), in a SOT-223. 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 | GND | power_in | Ground pin of the fixed-voltage version (地), the common return for the 5.0V regulator. |
| 2 | Vout | power_out | Regulated 5.0V output; the datasheet specifies 4.900 to 5.100 V at Iout = 10 mA, 0 to 1.0 A, 6.5 V ≤ Vin ≤ 12 V, and recommends a 22 µF tantalum capacitor from Vout to GND for stability. |
| 3 | Vin | power_in | Input pin; the absolute maximum input voltage is 18 V and the recommended input range is up to 15 V, with a 10 µF tantalum input bypass recommended. |
