DESCRIPTION

PIN CONFIGURATIONS
The TL431 and TL431A are 3-terminal adjustable shunt regulators
with specified thermal stability over applicable automotive and
commercial temperature ranges. The output voltage may be set to
any value between VREF (approximately 2.5V) and 36V with two
external resistors (see Figure 4). These devices have a typical
output impedance of 0.2Ω. Active output circuitry provides a very
sharp turn-on characteristic, making these devices excellent
replacements for zener diodes in many applications like on-board
regulation, adjustable power supplies and switching power supplies.

NOTES:
2. Full temperature range is –40°C to +85°C for the TL431I and TL431AI, and 0°C to +70°C for the TL431C and TL431AC.
3. The deviation parameters VREF(dev) and IREF(dev) are defined as the differences between the maximum and minimum values obtained over
the rated termperature range. The average full-range temperature coefficient of the reference input voltage, αVREF, is defined as:
| V REF |

αVREF can be positive or negative depending on whether minimum VREF of maximum VREF, respectively, occurs at the lower temperature.
Example: Max VREF = 2496mV at 30°C, Min VREF = 2492mV at 0°C, VREF = 2495mV at 25°C, DTA = 70°C for TL431C.

Because minimum VREF occurs at the lower temperature, the coefficient is positive.
