TLV73333PQDBVRQ1

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

TLV73333PQDBVRQ1 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, 1.4 V to 5.5 V operating range (absolute max 6.0 V). A small ceramic capacitor from IN to GND is recommended for source-impedance decoupling, though the device is stable without one.
2 GND power_in Device ground reference. All voltages are measured with respect to this pin.
3 EN input Active-high enable input. Drive above VEN(HI) to turn on the regulator; drive below VEN(LO) to place the LDO into shutdown mode (active output discharge engages). Must not be left floating.
4 NC unconnected No internal connection. May be left floating or tied to any convenient net for routing.
5 OUT power_out Regulated 3.3 V output pin, 300 mA source capability, 1% typical accuracy (1.4% max). For best transient response, TI recommends a small 1 µF ceramic capacitor from OUT to GND, although the device is stable capacitor-free.

Provenance

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

  • Datasheet: Texas Instruments datasheet (None pp, sha256 9c366ae4d9e9b906, 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.
