Silicore(芯谷) · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223
D1117-ADJ 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 | Adj | passive | Adjustment pin of the adjustable version, which sets the output through external resistors R1 and R2 with a typical adjust current of 55 µA (max 120 µA), and a bypass capacitor Cadj to ground is recommended to reduce ripple amplification. |
| 2 | Vout | power_out | Regulated output pin that delivers up to 1.0 A with 1.25 V to 13.8 V adjustable output, and a 22 µF tantalum capacitor to ground is recommended for stability. |
| 3 | Vin | power_in | Unregulated input pin with an absolute maximum rating of 18 V and a recommended input voltage range up to 15 V, and a 10 µF tantalum input bypass capacitor is recommended. |
