Overview
The HA17431GPA-E is a temperature-compensated variable shunt regulator manufactured by Renesas Electronics Corporation. It functions as a high-precision voltage reference and adjustable regulator, typically providing a nominal output of 2.5V with ±1% accuracy at 25°C. The device utilizes a miniature package optimized for high mounting density circuit boards. It incorporates an on-chip high-precision reference voltage source and is designed for applications requiring stable voltage regulation in compact electronic systems.
Feature Summary
- Temperature-compensated variable shunt regulation architecture
- High-precision internal reference voltage source
- Miniature package design suitable for high-density PCBs
Applications
- Voltage regulators providing variable output voltage
- Switching mode power supplies
- General-purpose voltage reference circuits
Procurement Notes
Verify the specific suffix 'GPA' against official Renesas documentation to confirm pinout compatibility and package dimensions, as variations exist within the HA17431 series. Ensure the component meets required automotive or industrial qualification standards if applicable to your design. Cross-reference datasheets for thermal characteristics and maximum operating voltages before finalizing procurement specifications.
Selection Notes
Select this component when a compact, high-precision shunt regulator is required for space-constrained designs. It is suitable for applications needing a stable 2.5V reference with low temperature drift. Consider package availability and lead times relative to other variants in the HA17431 family to ensure supply chain stability for production volumes.
Part Context
The HA17431 series represents a line of temperature-compensated variable shunt regulators originally developed by Hitachi Semiconductor and now produced by Renesas Electronics. These devices are widely used in precision analog circuits where a stable reference voltage is critical. The series includes various package options to accommodate different board space requirements and thermal management needs.
Replacement Considerations
Compatible substitutes include other HA17431 variants such as HA17431FPA-E or HA17431HLTP-E, provided pinouts and package types match. Verify electrical parameters like reference voltage tolerance and temperature coefficient to ensure functional equivalence in the target application.
