HA17431H Series
Shunt Regulator
ADE-204-070 (Z)
Preliminary
Rev.0
Sep. 2001
Description
The HA17431H series is a family of voltage referenced shunt regulators. The main application of these
products is in voltage regulators that provide a variable output voltage. The HA17431H series products are
provided in a wide range of packages; TO-92 insertion mounting packages and MPAK-5 (5 pin), MPAK (3
pin), UPAK surface mounting packages are available. The on-chip high-precision reference voltage source
can provide 1% accuracy, which have a V
KA
max of 36 volts.
Features
The reference voltage provide 2.500 V 1% at Ta = 25C
The reference voltage has a low temperature coefficient
The MPAK-5 (5 pin), MPAK (3 pin) and UPAK miniature packages are optimal for use on high
mounting density circuit boards
