Purchasing and Inquiry
TL431AQDBZRQ1 Description
The TL431AQDBZRQ1 is a three-pin adjustable shunt regulator that has been tested for thermal stability across a wide range of automotive temperature ranges. With two external resistors, the output voltage can be tuned to any value between VREF (about 2.5 V) and 36 V. (see Figure 28). The output impedance of this device is typically 0.2. In many applications, such as onboard regulation, adjustable power supplies, and switching power supplies, active output circuitry provides a sharp turnon characteristic, making this device an appropriate replacement for Zener diodes.
TL431AQDBZRQ1 Features
? Low noise output
? 0.2-0.3 Impedance of a typical output
? 1 mA to 100 mA sink-current capabilities
? VREF to 36 V adjustable output voltage
TL431AQDBZRQ1 Applications
? Voltage and current references that can be adjusted
? In flyback SMPSs, secondary side regulation is important.
? Replacement of the zener
? Voltage measurement
? A comparison tool with a built-in reference
