TL431

1 Orders 0 Wish listed

The TL431 is a versatile programmable reference voltage device often used in power supply regulation and various electronic applications. Here are the key features and details:

Specifications:

Type: Adjustable voltage reference (shunt regulator)
Output Voltage Range: Typically adjustable from 1.25V to 36V.
Tolerance: Generally around ±1% for the reference voltage.
Output Current: Can sink up to 100 mA.

Features:

Programmable: The output voltage can be set using two external resistors, making it customizable for different applications.
Low Output Impedance: Provides good regulation, making it suitable for precision applications.
Temperature Stability: Offers stable performance over a wide temperature range.
Compact Package: Available in various package types, including TO-92, SOIC, and others.

Applications:

Power Supply Circuits: Used as a voltage reference in switch-mode power supplies (SMPS) and linear regulators.
Feedback Control: Commonly found in voltage feedback loops for maintaining stable output voltage.
Battery Management: Can be used in battery chargers for voltage regulation.
Instrumentation: Useful in measurement devices where a precise reference voltage is necessary.

Example Application Circuit:

To set a specific output voltage (Vout), you typically use the formula: $V_{out} = V_{ref} \left(1 + \frac{R_2}{R_1}\right) + I_{ref} \times R_2$ where:

$V_{ref}$ is typically 1.25V,
$R_1$ and $R_2$ are the resistors connected to the device.

Considerations:

Power Dissipation: Be mindful of the power rating of the resistors and the TL431 itself to prevent overheating.
Input / Output Isolation: Ensure that the load does not exceed the current specifications.
