TLV74311PDBVR

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

TLV74311PDBVR from Texas Instruments, in a SOT-23-5. 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. Recommended range 1.4 V to 5.5 V (absolute max 6 V). Bypass with a small ceramic capacitor to GND close to the pin.
2 GND power_in Device ground reference pin. Connect to the system ground plane.
3 EN input Enable input. Drive EN above V_EN(HI) to turn the regulator on; drive below V_EN(LO) to place the LDO in shutdown. EN operating range 0 V to V_IN (absolute max V_IN + 0.3 V).
4 NC unconnected No internal connection. May be left floating or tied to GND for layout convenience.
5 OUT power_out Regulated output voltage pin (1.1 V nominal for TLV74311P variant), rated 300 mA. Requires a 1-µF ceramic output capacitor to GND for stability and best transient response.

CAD (KiCad official)

  • Symbol: TLV74311PDBVR
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: tlv74311pdbvr-etched.step / tlv74311pdbvr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tlv74311pdbvr.step / tlv74311pdbvr.glb are the bare package body.

Provenance

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

  • Datasheet: Texas Instruments datasheet (38 pp, sha256 231363715fb5480e, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
