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鈥檚 UPAK products.
