Description
The HA17L431LP(MPAK-5) / P(TO-92) / UP(UPAK) and the HA17L431ALP(MPAK-5) / AP(TO-92) are
temperature-compensated variable shunt regulators. These ICs can operate at about half voltage in
comparison with HA17431V series. They can be replaced for simple Zener diode and they can also be
used for switching power supply secondary-side error amplification circuit. MPAK-5, TO-92 and UPAK
packages are available. The MPAK-5 package, in particular, is suitable for high-density mounting, with a
mounting area approximately half that of Hitachi’s UPAK products.
