1 / 25 page TLVH431A-Q1 TLVH431B-Q1 www.ti.com SLVS906B – DECEMBER 2008 – REVISED MARCH 2011 LOW-VOLTAGE ADJUSTABLE PRECISION SHUNT REGULATORS Check for Samples: TLVH431A-Q1, TLVH431B-Q1 1 FEATURES • Qualified for Automotive Applications • Low-Voltage Operation: Down to 1.24 V • Reference Voltage Tolerances at 25 °C – 0.5% for B Grade – 1% for A Grade • Adjustable Output Voltage, VO = VREF to 18 V • Wide Operating Cathode Current Range: 100 μA to 70 mA • 0.25- Ω Typical Output Impedance • –40°C to 125°C Specifications DESCRIPTION/ORDERING INFORMATION The TLVH431 devices are low-voltage 3-terminal adjustable voltage references, with thermal stability specified over the automotive temperature range. Output voltage can be set to any value between VREF (1.24 V) and 18 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. When used with an optocoupler, the TLVH431 devices are ideal voltage reference in isolated feedback circuits for 3-V to 3.3-V switching-mode power supplies. They have a typical output impedance of 0.25 Ω. Active output circuitry provides a very sharp turn-on characteristic, making the TLVH431 an excellent replacement for low-voltage Zener diodes in many applications, including on-board regulation and adjustable power supplies.
