TLVH431LIL5T

STMicroelectronics · Voltage Reference · SOT-23-5L

TLVH431LIL5T from STMicroelectronics, in a SOT-23-5L. 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 NC unconnected No internal connection. Leave floating or tie to a convenient net; not electrically bonded to the die.
2 NC unconnected No internal connection. Leave floating or tie to a convenient net; not electrically bonded to the die.
3 Cathode passive Cathode (K) of the shunt reference. Sinks the regulated current (Ik = 100 uA to 60 mA) from the supply through a series resistor; VKA can be set from Vref (1.24 V) up to 18 V. Absolute maximum VKA = 22 V; continuous cathode current limited to +/-100 mA.
4 Ref input Reference input (feedback). Internal error amplifier drives the cathode to hold this pin at Vref = 1.24 V typical. Tie directly to cathode for a fixed 1.24 V reference, or to the tap of an R1/R2 divider from cathode to anode to set VKA = Vref*(1+R1/R2)+R1*Iref. Iref = 1.5 uA typ, 2.5 uA max; absolute maximum -0.05 to +3 mA.
5 Anode passive Anode (A) of the shunt reference; the low-side return, normally tied to circuit ground in a standard shunt-regulator topology.

Provenance

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

  • Datasheet: STMicroelectronics datasheet (15 pp, sha256 0f9228f5a3cc7573, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
