BD26503KS2-ZAE2

Display Drivers Overview

The BD26503KS2-ZAE2 is an LED driver integrated circuit manufactured by Rohm Semiconductor, specifically designed for dot matrix display applications. It operates within a supply voltage range of 4.5 V to 8 V and delivers a fixed output current of 1 A. The device features high output accuracy of +/-3% across an operating temperature range of -40°C to +105°C. Packaged in the compact HTSOP-J8 format, it exhibits a typical dropout voltage of 600 mV and maximum power dissipation of 2.11 W. Line and load regulation are specified at 25 mV each, with an input bias current of 900 uA.

Display Drivers Feature Summary

• Integrated high-accuracy linear regulation suitable for automotive environments
• Compact surface-mount packaging with enhanced thermal resistance
• Optimized for low standby power consumption in dot matrix displays

Display Drivers Applications

• Automotive dot matrix display systems
• Vehicle instrument cluster illumination
• High-reliability indicator lighting circuits

Display Drivers Procurement Notes

Verify the complete part number including the suffix CE2 against official Rohm documentation to ensure correct package type and automotive grade specifications. Confirm RoHS compliance status through the manufacturer's latest datasheet. Validate that the HTSOP-J8 footprint matches your PCB design requirements before ordering. Check for any specific delivery restrictions or regional availability limitations imposed by distributors.

Display Drivers Selection Notes

Select this component when a fixed 5 V output with 1 A capacity is required for automotive-grade LED driving. Ensure the input voltage remains between 4.5 V and 8 V to maintain proper regulation. Consider the thermal performance given the 2.11 W dissipation limit in the small HTSOP-J8 package. Verify that the +/-3% accuracy meets your display brightness uniformity standards across the full industrial temperature range.

Display Drivers Part Context

This LDO regulator belongs to ROHM's series of integrated MOSFET DC-DC converters and voltage controllers, though it functions as a linear device rather than a switching converter. It complements other automotive power management ICs by providing stable, low-noise power for sensitive display logic and LED arrays where switching noise must be minimized.

Display Drivers Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Consult Rohm Semiconductor directly for cross-reference information or equivalent automotive-grade LDO regulators with matching pinouts and electrical characteristics.
