ISL9000IRMNZ

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

The ISL9000IRMNZ is a dual-output positive fixed linear low-dropout (LDO) voltage regulator manufactured by Renesas Electronics Corporation. It provides two independent output channels, each capable of delivering up to 300mA of load current. The device features a maximum input voltage rating of 6.5V and offers fixed output voltages of 2.8V and 3V. It incorporates comprehensive protection mechanisms including overcurrent limiting, thermal shutdown, and undervoltage lockout (UVLO). The component operates within an extended temperature range of -40°C to +85°C and is housed in a compact 10-DFN (3x3mm) surface-mount package with an exposed pad for enhanced thermal performance.

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

Verify the specific output voltage configuration required for your application, as the ISL9000 series includes variants with different fixed voltage combinations such as 3.3V/3.3V or 3V/3V. Confirm that the 10-DFN footprint matches your board design constraints. Note that availability may be limited due to end-of-life status; check for active stock or qualified replacement components before finalizing procurement plans.

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

Select this component when dual isolated LDO outputs are needed from a single source to save board space. Ensure the input voltage does not exceed 6.5V and that the total load current per channel remains within the 300mA limit. Consider the thermal dissipation requirements given the small package size and verify compatibility with the system's operating temperature range.

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

This part belongs to the ISL9000 series of dual LDO regulators designed for portable electronics. It shares common family features like low noise and high PSRR but differs in fixed output voltage settings. The manufacturer has indicated end-of-life status for many variants in this series, impacting long-term supply chain stability for new designs.

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

Check for direct pin-compatible alternatives within the same ISL9000 family that match the required output voltages. Verify if newer generation PMICs from Renesas offer similar dual-output capabilities with improved efficiency or additional features while maintaining the same package outline.
