Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223-4

TLV1117LV18DCYR from Texas Instruments, in a SOT-223-4. 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 for the regulator. All voltages are referenced to this pin.
2 OUT power_out Regulated 1.8-V output pin (±1.5% accuracy, up to 1-A continuous). Requires a 1-µF ceramic output capacitor (0-Ω ESR acceptable) for stability. Pin 2 is electrically connected to the SOT-223 tab.
Tab OUT power_out SOT-223 thermal tab, electrically connected to OUT (pin 2). Serves as the primary heat-spreading path; tie to the OUT copper pour for thermal dissipation.
3 IN power_in Unregulated input supply pin, 2 V to 5.5 V (absolute max 6 V). Requires a 1-µF ceramic input capacitor close to the pin.
