Texas Instruments TL431

GULL WING Non-RoHS Compliant DUAL BIPOLAR voltage reference device 2.92mm 1.12mm 92ppm/C 36V

the tl431 and tl432 are three-terminal adjustable shunt regulators with specified thermal stability over applicable automotive commercial and military temperature ranges. the output voltage can be set to any value between vref (approximately 2.5 v) and 36 v with two external resistors (see figure 17). these devices have a typical output impedance of 0.2 . active output circuitry provides a very sharp turn-on characteristic making these devices excellent replacements for zener diodes in many applications such as onboard regulation adjustable power supplies and switching power supplies. the tl432 has exactly the same functionality and electrical specifications as the tl431 but has different pinouts for the dbv dbz and pk packages. view all in datasheet
