ISL9000AIRMMZ-T

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

The ISL9000AIRMMZ-T is a dual low-dropout (LDO) linear voltage regulator manufactured by Renesas Electronics. It provides two independent fixed output voltages of 1.8V and 3.3V, each capable of sourcing up to 300mA. The device operates with an input voltage range from 2.3V to 6.5V. Key electrical specifications include a typical dropout voltage of 250mV at 300mA load, a quiescent current of 32µA, and power supply rejection ratio (PSRR) values of 90dB at 1kHz and 50dB at 100kHz. It features a 10-lead DFN package measuring 3x3mm.

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

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential counterfeit risks. Confirm the specific suffix 'AIRMMZ-T' matches design requirements, as variations exist within the ISL9000 family. Check for end-of-life status or obsolescence notices from Renesas before finalizing procurement plans. Ensure RoHS compliance documentation is available if required by regulatory standards.

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

Select this component when dual isolated LDO outputs are needed in a compact footprint. The 300mA per channel rating suits moderate current loads. Consider the 1.8V/3.3V fixed output combination; alternative models offer different voltage pairs. Evaluate thermal performance given the small DFN package size under maximum load conditions. Verify that the input voltage range covers the system's minimum and maximum supply levels.

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

This part belongs to the ISL9000A series of high-performance dual LDO regulators. It is designed for applications demanding low noise and high PSRR. The series typically includes variants with different output voltage combinations and packaging options. Renesas acquired Intersil, which originally developed this product line, hence branding may vary between Renesas and Intersil references.

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

Check for direct pin-compatible substitutes within the ISL9000 family offering different output voltages. Verify equivalent electrical characteristics such as dropout voltage and quiescent current. Ensure the replacement maintains the same 10-DFN 3x3mm package dimensions for mechanical compatibility.
