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.
