Frequently Asked Questions
What is the output voltage range of the TL431ACDBVR?
The TL431ACDBVR supports an adjustable output voltage range from 2.495V (the internal reference voltage) up to 36V. The output voltage is set using two external resistors connected to the REF pin, making it flexible for a wide variety of power supply and voltage reference applications.
What is the maximum output current the TL431ACDBVR can sink?
The TL431ACDBVR can sink a maximum cathode current of 100mA (0.1A). This makes it suitable for use as a shunt regulator in low to medium current applications such as power supply feedback circuits, battery chargers, and precision voltage references.
What package does the TL431ACDBVR come in and what are its dimensions?
The TL431ACDBVR is available in a SOT-23-5 (DBV) 5-pin small outline transistor package. This compact surface-mount package is ideal for space-constrained PCB designs in portable and consumer electronics, measuring approximately 1.6mm x 2.9mm.
What is the reference voltage accuracy of the TL431ACDBVR?
The TL431ACDBVR offers 1% initial accuracy on its 2.495V internal reference voltage. This level of precision makes it suitable for applications that require tight voltage tolerances, such as precision power supplies, instrumentation, and analog signal conditioning circuits.
Can the TL431ACDBVR replace other shunt regulators like the TLV431 or LM431?
The TL431ACDBVR is pin-compatible with many standard TL431 variants. The TLV431 operates at a lower reference voltage (1.24V) and lower supply, so it is not a direct drop-in replacement. The LM431 is functionally equivalent in most applications, but verify voltage accuracy, temperature range, and package compatibility before substituting.
