HA17L431 Series
High-Precision Variable Shunt Regulators
ADE-204-029B (Z) 3rd Edition Apr. 1999 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.

Marking Pattern on MPAK-5 Models (HA17L431LP) and UPAK Models (HA17L431UP, HA17L432UP)
Because of the small package size, the following marking patterns are used on MPAK-5 and UPAK models. Note that the product code and marking pattern are different. The patterns are laser-marked.
