HA17L431 Series
High-Precision Variable Shunt Regulators
Description
The HA17L431LP(MPAK-5) / P(TO-92) / UP(UPAK) 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.
