Description

TLVH431BIL3T is TI’s TLV431 family programmable shunt regulator (a precision adjustable Zener). It provides a 2.495 V reference and sinks current from the cathode to hold the REF pin at Vref. With an external resistor divider from the cathode to ground connected to REF, you set the output voltage: Vout ≈ Vref × (1 + R1/R2). It operates from a few volts up to about 36 V, with cathode current ranging from microamps to tens of milliamps in regulation. The device is three-terminal and lead‑free, packaged in a small SOT‑23/SC‑70 style in Tape & Reel (IL3T). Applications include precision voltage references for ADCs, post-regulation in linear regulators, and simple overvoltage/bower regulation in battery and power-management circuits.

Features

Here are the key features of TLVH431BIL3T (precision adjustable shunt regulator in a 3-pin package):
- Precision adjustable shunt regulator with a stable reference (Vref ~2.495 V)
- External resistor divider programs the output voltage (Vout = Vref(1+R1/R2) + Iadj·R1)
- Wide operating voltage (up to ~36 V) and broad current range for regulation (typical min cathode current ~1 mA; max around 100 mA)
- Excellent line and load regulation with low dynamic impedance
- High temperature stability and accuracy suitable for references and voltage regulation
- Protective features: current limit and thermal shutdown
- Packaging: Pb-free, tape-and-reel options in a 3‑lead package (SOT-23 style family variant)
Note: exact temperature range and spec values depend on the specific lot/grade; automotive/industrial grades may offer extended temp ranges (e.g., -40°C to 125°C).

Package

TLVH431BIL3T is offered in an 8-pin VSSOP (VSSOP-8) package, lead-free. For exact package code and pinout, please refer to the TI datasheet.

Pinout

- Pin count: 3 pins (SOT-23-3 package)
- Function: Adjustable precision shunt regulator (programmable voltage reference). It has Cathode (K), Anode (A), and Reference (R) terminals; maintains a fixed reference (≈2.495 V) and uses an external resistor divider to set the regulation threshold by shunting current.

Manufacturer
