ISL9000AIRMMZ

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

The ISL9000AIRMMZ is a dual low-dropout (LDO) linear voltage regulator manufactured by Renesas Electronics Corporation. It provides two independent positive fixed output channels, specifically configured for 2.5V and 3.0V outputs. Each channel is capable of sourcing up to 300mA of load current. The device operates with an input voltage range from 2.3V to 6.5V. Key electrical parameters include a maximum dropout voltage of 400mV at full load, a typical quiescent current of 32µA, and a maximum supply current of 52µA. It features integrated protection mechanisms including overcurrent, thermal shutdown, and undervoltage lockout (UVLO). The component utilizes a 10-pin VFDFN package with dimensions of 3.00mm x 3.00mm and a height of 0.88mm, suitable for surface mount installation across an operating temperature range of -40°C to +85°C.

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

Verify the specific output voltage configuration (2.5V/3.0V) against the suffix code on the physical component or official datasheet, as suffixes determine the fixed output levels. Confirm package type compatibility with your PCB footprint. Check for End-of-Life (EOL) status or obsolescence notices from Renesas, as this series may have discontinuation updates. Ensure RoHS compliance requirements are met if applicable to your manufacturing standards.

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

Select this component when a dual-output LDO solution is required with fixed 2.5V and 3.0V rails. It is suitable for designs needing high PSRR and low noise. Consider the 300mA per channel limit for load requirements. The 10-VFDFN package is ideal for space-constrained boards. Verify that the input voltage remains within the 2.3V to 6.5V range under all operating conditions.

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

The ISL9000AIRMMZ belongs to the ISL9000A family of dual LDO regulators from Renesas (formerly Intersil). This family is characterized by low noise, very high Power Supply Rejection Ratio (PSRR), and low quiescent current. Other variants in the series offer different fixed output combinations, such as 2.7V/3.0V or 2.85V/2.85V, sharing similar protection features and packaging options.

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

Check for direct substitutes within the ISL9000A family with matching output voltages (e.g., ISL9000AIRMGZ for 2.7V/3.0V if adjustable). Verify pin-to-pin compatibility with other dual LDOs in the 10-DFN package. Consult Renesas documentation for any recommended replacements due to EOL status.
