HIP5600IS2

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The HIP5600IS2 is a high-voltage, adjustable three-terminal positive linear voltage regulator manufactured by Harris Corporation. It operates from input voltages ranging from 50VDC to 400VDC or 50VRMS to 280VRMS. The output voltage is adjustable from 1.2VDC up to within 50V of the peak input voltage using two external resistors. The device can source continuous currents between 1mA and 30mA with appropriate heat sinking, and provides up to 40mA peak output current for short durations. It features internal thermal shutdown and over-current protection circuits.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Capable of withstanding input-to-output voltages as high as 400V peak, even under output short-circuit conditions.
• Surge rated to ±650V, meeting IEEE/ANSI C62.41.1980 standards when used with additional MOV components.
• Integrates on-chip thermal shutdown and output current limiting circuitry for robust protection.

• Switch Mode Power Supply Start-Up
• Electronically Commutated Motor Housekeeping Supply
• Power Supply for Simple Industrial/Commercial/Consumer Equipment Controls
• Off-Line (Buck) Switch Mode Power Supply

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify that the specific order corresponds to the HIP5600IS2 variant, noting that manufacturer documentation lists multiple suffixes such as IS and IS2 under the same functional description. Confirm package type and temperature grade requirements against the official datasheet specifications before procurement. Ensure proper heat sinking is planned for the desired load current range.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component for applications requiring high-voltage regulation where standard regulators cannot handle the potential differential. It is suitable for AC/DC conversion and startup circuits in switch-mode power supplies. Note that the product does not provide isolation from the AC line; therefore, system design must account for safety isolation requirements separately.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

The HIP5600 series belongs to a family of thermally protected high-voltage linear regulators originally published by Intersil Corporation and Harris Corporation. The document revision history indicates updates to mechanical dimensions and ordering information over time. This specific part number represents a variant within the broader HIP5600 lineup designed for high-voltage industrial and commercial control environments.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. The datasheet lists related variants HIP5600 and HIP5600IS but does not explicitly define them as direct cross-references or replacements for the IS2 suffix.
