• Output Current Limited to 150 mA
• External Adjustment Pin
• High Accuracy: ±1%
• Low Output Voltage: ≤ 1.24 V

Applications

The TL431ACDBZT is widely used in various power management applications. It can be found in chargers, linear regulators, switching converters and other dc-dc converters. It is also used in power supply, motor control, telecommunication, portable electronic products.

Working Principle

The TL431ACDBZT is an adjustable shunt regulator with an external adjustment pin. Its working principle is based on the voltage divider principle. When a voltage is applied across the two terminals of the device, the output voltage of the device is adjusted by the ratio of the input voltage. The external adjustment pin allows the user to adjust the output voltage of the device by changing the resistance of the voltage divider.

The TL431ACDBZT also has a temperature coefficient of 0.15%, which ensures that the output voltage remains stable over temperature variations.
