HA17431H

Data Sheet HA17431H Series Shunt Regulator R03DS0088EJ0300 Rev.3.00 Jan 10, 2014 Description The HA17431H series is temperature-compensated variable shunt regulators. The main application of these products is in voltage regulators that provide a variable output voltage. The on-chip high-precision reference voltage source can provide ±1% accuracy, which have a VKA 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-5V (5 pin), MPAKV (3 pin) and UPAKV miniature packages are optimal for use on high mounting density circuit boards Block Diagram K REF + − 2.500 V A Application Circuit Example Switching power supply secondary-side error amplification circuit Vout R + R1 – K REF A R2 HA17431H Series GND R03DS0088EJ0300 Rev.3.00 Jan 10, 2014 Page 1 of 7 HA17431H Series Ordering Information Item Industrial use HA17431HLTP HA17432HLTP HA17431HLP HA17431HP HA17431HUP HA17432HUP Package Code (Previous Code) Temp.
