LD1117SG-3.3

BLUE ROCKET(蓝箭) · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223

LD1117SG-3.3 from BLUE ROCKET(蓝箭), 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/ADJ power_in Ground pin for the fixed-output LD1117SG-3.3, and the adjust pin on the LD1117SG-ADJ, where Iadj is 60 to 120 uA (typ./max as printed).
2 OUT power_out Regulated output, rated for output current up to 1.0 A with internal current and thermal limiting.
3 IN power_in Unregulated input supply; the LD1117SG-3.3 specifies Vin of 4.75 V to 15 V and the absolute maximum DC input voltage is 15 V.
