LR1117DD12X
LRC · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252
LR1117DD12X from LRC, in a TO-252. 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 reference pin for the fixed-voltage regulator; the datasheet gives no separate electrical limit for this pin. |
| 2 | Vout | power_out | Regulated 1.2V output for this fixed version, specified for output currents up to 1A with output voltage accuracy within ±2%. |
| 3 | Vin | power_in | Input supply pin, with recommended operating input voltage up to 15V (absolute maximum 18V), and a 10uF input capacitor recommended. |
