1 / 54 page  TLV431x Low-Voltage Adjustable Precision Shunt Regulator 1 Features • Low-voltage operation, VREF = 1.24V • Adjustable output voltage, VO = VREF to 6V • Reference voltage tolerances at 25°C – 0.5% for TLV431B – 1% for TLV431A – 1.5% for TLV431 • Typical temperature drift – 4mV (0°C to 70°C) – 6mV (–40°C to 85°C) – 11mV (–40°C to 125°C) • Low operational cathode current, 80µA typical • 0.25Ω typical output impedance • Ultra-small SC-70 package offers 40% smaller footprint than SOT-23-3 • See TLVH431 and TLVH432 for: – Wider VKA (1.24V to 18 V) and IK (80mA) – Additional SOT-89 package – Multiple pinouts for SOT-23-3 and SOT-89 packages • On products compliant to MIL-PRF-38535, all parameters are tested unless otherwise noted. on all other products, production processing does not necessarily include testing of all parameters. 2 Applications • Adjustable voltage and current referencing • Secondary side regulation in flyback SMPSs • Zener replacement • Voltage monitoring • Comparator with integrated reference Simplified Schematic 3 Description The TLV431 device 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 (1.24V) and 6V with two external resistors (see the Parameter Measurement Information section). These devices operate from a lower voltage (1.24V) than the widely used TL431 and TL1431 shunt-regulator references. When used with an optocoupler, the TLV431 device is an ideal voltage reference in isolated feedback circuits for 3V to 3.3V switching-mode power supplies. These devices have a typical output impedance of 0.25Ω. Active output circuitry provides a very sharp turnon characteristic, making them excellent replacements for low-voltage Zener diodes in many applications, including on-board regulation and adjustable power supplies.
