TLV431ACDBVR Datasheet

Low-Voltage Adjustable Precision Shunt Regulator


The TLV431ACDBVR 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 TL1431 shunt-regulator references. TLV431ACDBVR Features • Low-Voltage Operation...VREF= 1.24 V• Adjustable Output Voltage, VO = VREF to 6 V• Reference Voltage Tolerances at 25°C - 0.5% for TLV431B - 1% for TLV431A - 1.5% for TLV431• Typical Temperature Drift - 4 mV (0°C to 70°C) - 6 mV (–40°C to 85°C) - 11 mV (–40°C to 125°C)• Low Operational Cathode Current . . . 80 µA Typ• 0.25-ΩTypical Output Impedance• Ultra-Small SC-70 Package Offers 40% Smaller Footprint Than SOT-23-3• See TLVH431 and TLVH432 for - Wider VKA(1.24 V to 18 V) and IK(80 mA) - Additional SOT-89 Package - Multiple Pinouts for SOT-23-3 and SOT-89 Packages
