TYPICAL OUTPUT IMPEDANCE OF THE

TL431B LESS THAN 100m

Ω

W ADJUSTABLE OUTPUT VOLTAGE FROM 2.5V

TO 36V

W AVAILABLE IN SURFACE-MOUNT PACKAGES

W LOW OUTPUT NOISE

W TYPICAL EQUIVALENT FULL RANGE

TEMPERATURE COEFFICIENT OF 30ppm/°C

W DIRECT PIN-TO-PIN REPLACEMENT FOR

INDUSTRY STANDARD TL431 AND TL1431

The TL431/TL431A/TL431B series

precision adjustable three terminal shunt

voltage regulators are pin-to-pin

compatible with the industry standard

TL431. The output voltage of this

reference is programmable by using two

external resistors from 2.5V to 36V.

These devices offer low output

impedance for improved load regulation.

The typical output impedance of these

devices is 200m

Ω. These devices find

application in the feedback path of

switching power supplies, OVP

crowbar circuits, reference for A/D,

D/A, and as zener diodes with

improved turn-on characteristics.
