BL1117-12CY
BL Shanghai Belling · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252-2(DPAK)
BL1117-12CY from BL Shanghai Belling, in a TO-252-2(DPAK). 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-version regulator (BL1117-12V); the datasheet lists it as Ground for the fixed version. |
| 2 | Vout | power_out | Regulated 12V output of the BL1117-12V; the BL1117 series is rated for up to 1A load current with Cout=10uF recommended. |
| 3 | Vin | power_in | Unregulated input supply; the BL1117-12V maximum input voltage is 20V (other series versions are limited to 12V), with Cin=10uF recommended. |
