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 = 25°C
• 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
