LP1116-18G3F

LOWPOWER · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223

LP1116-18G3F from LOWPOWER, in a SOT-223. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 GND power_in Ground reference pin. Connect to system ground. Also acts as thermal path via the SOT-223 tab.
2 OUT power_out Regulated output pin, fixed 1.8V for LP1116-18G3F. Supplies up to 800mA (current-limited). Requires a 2.2µF ceramic output capacitor to GND for stability.
3 VIN power_in Power input pin, 2.5V to 6.5V operating range (7V absolute max). Requires a 2.2µF ceramic input capacitor to GND. Must be at least VOUT + dropout (≈480mV @ 600mA) for regulation.
