TLV431A Datasheet Low-voltage Adjustable Precision Shunt Regulator

Manufacturer: Texas Instruments

Overview: TLV431, TLV431A, TLV431B SLVS139Y – JULY 1996 – REVISED MARCH 2024 TLV431x Low-Voltage Adjustable Precision Shunt Regulator.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The TLV431 device is a low-voltage 3-terminal adjustable voltage reference with specified thermal stability over applicable industrial and commercial temperature ranges.

Output voltage can be set to any value between VREF (1.24V) and 6V with two external resistors (see the Parameter Measurement Information section).

These devices operate from a lower voltage (1.24V) than the widely used TL431 and TL1431 shunt-regulator references.

Key Features

  • Low-voltage operation, VREF = 1.24V.
  • Adjustable output voltage, VO = VREF to 6V.
  • Reference voltage tolerances at 25°C.
  • 0.5% for TLV431B.
  • 1% for TLV431A.
  • 1.5% for TLV431.
  • Typical temperature drift.
  • 4mV (0°C to 70°C).
  • 6mV (.
  • 40°C to 85°C).
  • 11mV (.
  • 40°C to 125°C).
  • Low operational cathode current, 80µA typical.
  • 0.25Ω typical output impedance.
  • Ultra-small SC-70 package o.
