0.4% Initial Voltage Tolerance
Sink Current Capability…1 mA to 100 mA
0.2- Typical Output Impedance
Low Reference Current (REF)
Fast Turnon…500 ns
Adjustable Output Voltage…V
I(ref) to 36 V
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
. 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.
