ISL9000AIRKFZ-T

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

The ISL9000AIRKFZ-T is a dual-channel low-dropout linear regulator manufactured by Renesas Electronics. It integrates two independent LDOs within a single 10-lead DFN package, delivering fixed output voltages of 2.5V and 2.85V with a maximum continuous current of 300mA per channel. The device operates from an input voltage range of 2.3V to 6.5V and maintains a typical dropout voltage of 250mV at full load. Designed for high performance, it features low output noise and high power supply rejection ratio (PSRR), ensuring stable regulation under varying load conditions.

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

• Integrates two independent high-performance LDO channels in a compact footprint

• Delivers very high PSRR for effective noise suppression in sensitive circuits
• Maintains extremely low quiescent current consumption for energy efficiency

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

• Portable battery-powered electronic devices requiring efficient power management
• Wireless communication modules needing low-noise voltage regulation
• Embedded systems utilizing microcontrollers or sensors with strict power constraints
• Industrial control units operating in environments with variable input voltages

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

Verify the specific suffix 'KFZ' to confirm the fixed output configuration of 2.5V and 2.85V, as other suffixes denote different voltage pairs. Confirm RoHS compliance status and check for End-of-Life notices, as this component series may have discontinuation announcements. Ensure the 10-DFN thermal pad soldering process aligns with your manufacturing capabilities to guarantee reliable heat dissipation during operation.

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

Select this component when space-constrained designs require dual regulated rails from a single IC. It is suitable for applications demanding low noise and high PSRR rather than high-current delivery. Compare against single-channel LDOs if only one rail is needed to optimize cost. Verify that the required output voltages match the available factory-set options, as adjustable versions are not included in this specific part number.

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

This device belongs to the ISL9000A series of dual LDO regulators designed for portable electronics. It replaces older discrete regulator solutions by integrating two channels into a small DFN package. The series emphasizes low noise and high PSRR, making it distinct from general-purpose regulators focused primarily on high current capacity.

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

Direct substitutes include other ISL9000A variants with matching output voltages, such as ISL9000IRKFZ. Cross-reference pinouts and thermal characteristics to ensure compatibility with existing PCB layouts without redesigning the power distribution network.
