汽车类低电压可调节精密并联稳压器(反向引脚排列) 3-SOT-23 -40 to 125
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 . 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.
