TL431ACLP Information

Description

The TL431ACLP is a precision adjustable shunt regulator from Texas Instruments, offering a wide range of output voltages (2.495V to 36V) with high accuracy and stability. It features overvoltage tolerance up to 42V, fault current limitation, and self-recovery ability from short-circuit faults. This device is suitable for various applications such as voltage regulation, current limiting, error amplification in power supplies, battery chargers, LED drivers, and audio amplifiers. Its compact TO-92 package provides high power density with a low dropout voltage of 1V at 5mA. The TL431ACLP also offers excellent noise rejection, line regulation, and temperature stability, making it an ideal choice for industrial control systems, automotive electronics, and consumer appliances requiring precise and stable voltage references or monitoring circuits.

Features

The TL431ACLP features include:

  • Safe Operating Area for Stress Protection
  • Overvoltage Tolerance to 42V Maximum
  • Fault Current Limitation of 1/1000 Typically
  • Compact Package with High Power Density
  • Fault-Protected Output for Overcurrent Condition
  • Self-Recovery Ability from Short-Circuit Faults
  • Output Voltage Accuracy Better Than 1%
  • Line Regulation of 20ppm/MV Typical
  • No Load Coefficient Less Than 10 ppm/C Typ

It also has programmable output current up to 10A, voltage tracking tolerance of +/- 0.4% Typ @ 25°C (TL431B), low input bias current typically, and economical and high-efficiency operation.

Additionally, it is short-circuit proof and overcurrent protected, with sink current capability of 100mA Typical, noise and ripple rejection better than 80 dB, and a response time to 100uS Typical.

Package

The package type of TL431ACLP is TO-92-3.

Pinout

The TL431ACLP has a 3-pin package (TO-92) with the following functions:

  • Pin 1: Output (Vout)
  • Pin 2: Input (Vin)
  • Pin 3: Ground (GND)

It is an adjustable voltage reference IC that provides a regulated output voltage, which can be programmed to a specific value. The device has overvoltage protection and fault current limitation features, making it suitable for use in power supplies, battery chargers, LED drivers, and other applications where stable voltage references are required.

Manufacturer

The manufacturer of the TL431ACLP is Texas Instruments (TI), a leading global semiconductor company that designs, manufactures, tests, and sells analog and embedded processing chips. TI is a well-established company with a rich history in the industry, founded in 1930 by J. Stewart Miller. Today, TI is a subsidiary of the Japanese conglomerate Toshiba Corporation.

Applications

The TL431ACLP is commonly used in applications such as:

  • Voltage regulation, current limiting, and error amplification in power supplies, battery chargers, LED drivers, and audio amplifiers.
  • Automotive electronics, industrial control systems, and consumer appliances for precise and stable voltage references and monitoring circuits.

Equivalent

According to Texas Instruments' datasheet, the equivalent products of TL431ACLP are:

  • TLV431 (surface-mount package)
  • TLV4931 (small outline diode package)
  • TLC27L5C (3-pin SOIC/TSSOP package)

Please note that these devices have similar specifications and functions as the TL431ACLP.

Package arrived 26 days after ordering. I haven't actually tested the modules' charging procedure this time but the voltages they provide are between 4.12-4.17V. They look ok.
