ISL9000IRJNZ-T

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

The ISL9000IRJNZ-T is a dual-output low-dropout (LDO) voltage regulator manufactured by Renesas Electronics. It integrates two independent linear regulators within a single 10-lead DFN package. The device provides fixed output voltages of 2.8V and 3.3V, with each channel capable of delivering up to 300mA of output current. It operates from an input voltage range of 2.3V to 6.5V. Key electrical characteristics include a maximum dropout voltage of 0.4V at 300mA load, a quiescent current of 32µA, and a line regulation accuracy of 0.8%. The component supports surface-mount installation and functions within a temperature range of -40°C to +85°C.

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

Verify the specific suffix configuration against the manufacturer's official datasheet to ensure correct output voltage selection and package type compatibility. Confirm that the intended application environment falls within the specified operating temperature range. Check for end-of-life status or alternative replacement recommendations from the supplier before finalizing procurement plans.

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

Select this component when a dual-rail power solution is required in a space-constrained design. It is suitable for applications demanding low noise and high power supply rejection ratio (PSRR). Ensure the input voltage remains within the 2.3V to 6.5V window and that the total load does not exceed the individual channel limits. Consider the thermal performance of the DFN package under maximum load conditions.

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

This part belongs to the ISL9000 series of dual LDO regulators designed for portable and industrial electronics. It replaces older discrete regulator solutions by integrating two channels into a single small outline package. The series is known for combining low noise performance with high PSRR, making it ideal for sensitive analog and digital circuits powered by single-cell lithium-ion batteries or similar sources.

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

Consult the manufacturer's obsolescence notices for direct pin-compatible substitutes. Verify that any alternative component matches the 10-DFN package dimensions and maintains equivalent electrical specifications for both output channels.
