HA17L431LP Datasheet High-precision Variable Shunt Regulators

Manufacturer: Hitachi Semiconductor (now Renesas)

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

General Description

The HA17L431LP(MPAK-5) / P(TO-92) / UP(UPAK) are temperature-pensated variable shunt regulators.

These ICs can operate at about half voltage in parison 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.
