TLV1117LV18DCYT

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

TLV1117LV18DCYT from Texas Instruments, in a SOT-223-4. 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, the reference for all voltage ratings (VIN and VOUT absolute maximum -0.3 V to 6 V with respect to GND).
2 OUT power_out Regulated output voltage pin, rated for 0 A to 1 A output current and 0 V to 5.5 V recommended, stable with a 1 µF ceramic output capacitor of 0-Ω ESR.
3 IN power_in Input supply pin with a recommended range of 2 V to 5.5 V and an absolute maximum of 6 V, used with a 1 µF input capacitor.
4 OUT power_out Tab of the SOT-223 package, which the datasheet lists as an additional OUT connection tied to the regulated output.
