Description
The UMW TL431 is an adjustable three-terminal shunt regulator with excellent thermal stability over operating temperature range.
The output voltage can be set to any value between Vref (approximately 2.5V) and 36V through external resistors.
Features
- Adjustable output voltage: up to 36V Low dynamic output impedance: 0.3Ω Sink current capability: 1.0~100mA Equivalent full-scale temperature coefficient: typ. 50ppm/°C Temperature compensation in the rated operating temperature range Low output noise Fast start-up response
