TFTL431

Shenzhen Tuofeng Semiconductor Technology Co., Ltd TFTL431 PROGRAMMABLE PRECISION REFERENCES The TL431 is three-terminal adjustable shunt regulator with specified termal stability. The output voltage may be set to any value between V REF(Approx. 2.5V) and 36V with two external resistors. This device has a typical output inpedance of 0.2Ω. Active output circuitry provides a very sharp turn-on characteristic, making this device excellent replacement for zener diodes in many application. TO-92 (TOP VIEW) 3. 2. 1. SOT-23 2.
