TLV117118DCYR

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

TLV117118DCYR 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 IN power_in Unregulated input supply pin. Operating range 2.0 V to 5.5 V (absolute maximum 6.0 V). Requires an input capacitor per the Input and Output Capacitor Requirements section.
2 GND power_in Device ground reference. Connect together with the tab (pin 4) to the system ground plane; the tab also serves as the primary thermal path.
3 OUT power_out Regulated 1.8 V output pin, capable of up to 1 A (current limit 1.1 A min). Requires an output capacitor per the Input and Output Capacitor Requirements section; stable with 0 Ω ESR ceramic caps and at 0 mA load.
4 GND power_in SOT-223 thermal tab, internally connected to GND. Solder to a copper ground pour to meet thermal dissipation requirements (θJA = 62.9 °C/W). TI counts the tab as pin 4 of the DCY package.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Texas Instruments datasheet (None pp, sha256 07cadfb0abee7939, retrieved 2026-08-17, tier: lcsc)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
