DESCRIPTION
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 2.5 V) and 36 V with two
external resistors (see Figure 4). 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 like on-board
regulation, adjustable power supplies and switching power supplies.
The TL431C and TL431AC are characterized for operation from
0
°C to +70 °C; the TL431I and TL431AI are characterized for
operation from –40
°C to +85 °C.
FEATURES
Equivalent full-range temperature coefficient: 30 ppm/°C
0.2 typical output impedance
Sink current capability: 1 mA to 100 mA
Low output noise
Adjustable output voltage: V
