HA17431HUPTL-E

Overview

The HA17431HUPTL-E is a temperature-compensated variable shunt regulator from the Renesas HA17431H series. It features an on-chip high-precision reference voltage source providing ±1% accuracy at 25°C, with a maximum cathode voltage (VKA) of 36 volts. The device operates within an industrial temperature range of -20°C to +85°C and utilizes the UPAKV miniature package, which is optimized for high mounting density circuit boards.

Feature Summary

• Temperature-compensated variable shunt regulation
• High-precision internal reference voltage source
• Optimized for high-density board mounting

Applications

• Voltage regulators providing variable output voltage
• Switching power supply secondary-side error amplification circuits

Procurement Notes

Verify the specific ordering suffix 'UPTL' against official Renesas documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with the UPAKV package dimensions and pinout configuration required by the target design.

Selection Notes

Select this component when a compact, temperature-stable shunt regulator is needed for precision voltage referencing. The UPAKV package suits designs requiring minimal footprint, while the 36V rating supports standard low-voltage power rails.

Part Context

This part belongs to the HA17431H series of shunt regulators manufactured by Renesas Electronics Corporation. The series includes variants in MPAK-5V, MPAKV, and TO-92V packages, all sharing the core temperature-compensated reference architecture.

Replacement Considerations

Compatible substitutes include other parts within the HA17431H series such as HA17431HLTP or HA17431HLP, provided the package form factor matches the existing PCB layout constraints.
