1 / 18 page TL1431 PRECISION PROGRAMMABLE REFERENCE SLVS062F – DECEMBER 1991 – REVISED JANUARY 2000 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D 0.4% Initial Voltage Tolerance D 0.2-Ω Typical Output Impedance D Fast Turnon . . . 500 ns D Sink Current Capability ...1 mA to 100 mA D Low Reference Current (REF) D Adjustable Output Voltage ...VI(ref) to 36 V description The TL1431 is a precision programmable reference with specified thermal stability over automotive, commercial, and military temperature ranges. The output voltage can be set to any value between VI(ref) (approximately 2.5 V) and 36 V with two external resistors (see Figure 16). This device has a typical output impedance of 0.2 Ω. Active output circuitry provides a very sharp turnon characteristic, making the device an excellent replacement for zener diodes and other types of references in applications such as onboard regulation, adjustable power supplies, and switching power supplies. The TL1431C is characterized for operation over the commercial temperature range of 0 °C to 70 °C. The TL1431Q is characterized for operation over the full automotive temperature range of –40 °C to 125°C. The TL1431M is characterized for operation over the full military temperature range of –55 °C to 125°C.
