ISL9000IRLLZ-T

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

The ISL9000IRLLZ-T is a dual-output low-dropout (LDO) linear voltage regulator manufactured by Renesas Electronics Corporation. It operates within an input voltage range of 2.3 V to 6.5 V and provides two fixed output voltages of 1.8 V and 2.5 V. Each channel supports a maximum output current of 300 mA. The device features a typical dropout voltage of 200 mV at full load, ensuring efficient regulation under varying conditions. It includes integrated protection mechanisms such as overcurrent limiting, thermal shutdown, and undervoltage lockout (UVLO). The component is housed in a compact 10-lead DFN package measuring 3 mm x 3 mm, suitable for space-constrained surface-mount applications.

• Comprehensive protection against overcurrent, thermal overload, and undervoltage conditions

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

• Portable electronic devices requiring multiple stable voltage domains
• Embedded systems utilizing microcontrollers with distinct core and I/O supply requirements
• Battery-powered equipment needing efficient linear regulation from single-cell sources

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

Verify the specific suffix 'IRLLZ' against official Renesas documentation to confirm the exact output voltage combination of 1.8 V and 2.5 V. Confirm the package type is indeed the 10-DFN variant. Check for any recent Product Change Notices or End-of-Life announcements, as older Intersil/Renesas components may have limited availability or require substitution planning.

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

Select this component when a dual-rail solution is required from a single input source without the complexity of switching regulators. Ensure the input voltage remains above the minimum threshold of 2.3 V while accounting for dropout margins. Verify that the total power dissipation stays within the thermal limits of the 3x3 mm DFN package under expected ambient temperature conditions.

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

This part belongs to the ISL9000A series of low-noise, high-PSRR LDOs originally developed by Intersil and later acquired by Renesas. The series is designed for sensitive analog and digital circuits requiring clean power supplies. The IRLLZ designation specifically identifies the fixed output voltage configuration and the tape-and-reel packaging format for automated assembly.

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

Consult the official Renesas ISL9000 datasheet for direct pin-compatible alternatives with different fixed output voltages, such as ISL9000IRNJZ-T or ISL9000IRJBZ-T. Cross-reference with newer Renesas PMIC families if long-term supply assurance is required, as legacy Intersil parts may be subject to discontinuation.
