Description

The TLV431AIDR is a low-voltage 3-terminal adjustable voltage reference with specified thermal stability over applicable industrial and commercial temperature ranges. Output voltage can be set to any value between VREF (1.24 V) and 6 V with two external resistors (see Figure 2). These devices operate from a lower voltage (1.24 V) than the widely used TL431 and TLV431AIDR shunt-regulator references. When used with an optocoupler, the TLV431 is an ideal voltage reference in isolated feedback circuits for 3-V to 3.3-V switching-mode power supplies. These devices have a typical output impedance of 0.25 Ω. Active output circuitry provides a very sharp turn-on characteristic, making them excellent replacements for low-voltage Zener diodes in many applications, including on-board regulation and adjustable power supplies. TLV431AIDR Features • Low-Voltage Operation ...VREF = 1.24 V• Adjustable Output Voltage, VO = VREF to 6 V• Reference Voltage Tolerances at 25C− 0.5% for TLV431B− 1% for TLV431A− 1.5% for TLV431• Low Operational Cathode Current . . .80 µA Typ• 0.25-Ω Typical Output Impedance• Ultra-Small SC-70 Package Offers 40% Smaller Footprint Than SOT-23-3
