HA17431 Series
Shunt Regulator
Description
The HA17431 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 HA17431 series products are
provided in a wide range of packages; TO-92 and TO-92MOD insertion mounting packages and MPAK-5,
UPAK, and FP-8D surface mounting packages are available. The on-chip high-precision reference voltage
source can provide ±1% accuracy in the V versions, which have a V
KA
max of 16 volts. The
HA17431VLP, which is provided in the MPAK-5 package, is designed for use in switching mode power
supplies. It provides a built-in photocoupler bypass resistor for the PS pin, and an error amplifier can be
easily constructed on the supply side.
Features
The V versions provide 2.500 V ±1% at Ta = 25°C
The HA17431VLP includes a photocoupler bypass resistor (2 k
)
The reference voltage has a low temperature coefficient
The MPAK-5 and UPAK miniature packages are optimal for use on high mounting density circuit
boards
A wide operating temperature range (–40 to +85°C) is provided by the TO-92, TO-92MOD, and FP-8D
package versions
