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
. 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.
