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

TLV1117LV28DCYR 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 pin. Common return for the regulator; connect directly to the system ground plane.
2 OUT power_out Regulated 2.8V output pin. Requires a 1 µF (min) ceramic output capacitor for stability; delivers up to 1A of load current with typical dropout of 455 mV at 1A (Vout ≥ 3.3V) / 570 mV at 1A (Vout < 3.3V).
3 IN power_in Unregulated input pin. Operates from 2V to 5.5V (absolute max 6V). Bypass with a 1 µF ceramic capacitor close to the pin.
Tab OUT power_out SOT-223 heat-slug tab, electrically connected to the OUT pin. Solder to a copper pour for thermal dissipation (θJA = 62.9 °C/W).
