HITACHI HA17431PA

HA17L431/HA17L431A Series
High-Precision Variable Shunt Regulators
ADE-204-029D (Z)
Rev.4
Dec. 2000
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.

Marking Pattern on MPAK-5 Models (HA17L431LP/HA17L431ALP) 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.
