ISL9000AIRJRZ-T

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

The ISL9000AIRJRZ-T is a dual-output low-dropout linear regulator manufactured by Renesas Electronics. It features two positive fixed outputs of 1.8V and 2.8V, each capable of delivering up to 300mA. The device operates within an input voltage range of 2.3V to 6.5V and maintains a maximum dropout voltage of 0.4V at 300mA load. It includes integrated protection mechanisms such as overcurrent, thermal shutdown, and undervoltage lockout. The component is housed in a compact 10-DFN (3x3) package with an exposed pad for enhanced thermal performance.

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

This component is officially classified as End-of-Life (EOL) by the manufacturer. Distribution channels indicate discontinuation status, meaning new production units are unavailable through standard supply chains. Engineers must verify current stock availability carefully and anticipate potential sourcing difficulties from authorized distributors. Procurement planning should prioritize immediate inventory acquisition or transition strategies to mitigate supply chain risks associated with obsolete parts.

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

Designers should evaluate the fixed output voltages of 1.8V and 2.8V against system requirements, as adjustable variants are not available in this specific suffix configuration. The 300mA per channel limit dictates suitability for low-to-moderate power loads. Thermal management considerations are critical due to the small DFN footprint; adequate PCB copper area is necessary to dissipate heat effectively under full load conditions while maintaining operational reliability.

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

The ISL9000AIRJRZ-T belongs to the ISL9000A series of dual LDO regulators. This family is characterized by high power supply rejection ratio and low noise performance suitable for sensitive analog circuits. The 'AIR' suffix denotes automotive-grade qualification and extended temperature range capabilities. The 'JC' variant specifically indicates the 1.8V/2.8V output combination, distinguishing it from other fixed-voltage options within the broader product line.

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

Public documentation confirms that the ISL9000AIRBBZ-T and ISL9000AIRFJZ-T are alternative part numbers within the same discontinued series. These substitutes offer different fixed output voltage combinations but share identical pinouts and functional characteristics. Designers may consider these cross-references if their circuit design allows for adaptation to the specific voltage levels provided by those variants.
