ISL9000IRMMZ-T

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

The ISL9000IRMMZ-T is a dual-output low dropout linear regulator manufactured by Renesas Electronics Corporation. It integrates two independent LDOs, each capable of delivering up to 300mA of output current. The device operates with an input voltage range from 2.3V to 6.5V and provides fixed positive output voltages of 3V and 3V. It features a typical dropout voltage of 200mV at full load and maintains excellent load regulation of less than 0.1%. The component is housed in a compact 10-DFN (3x3mm) package with an exposed pad for thermal dissipation.

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

Verify the specific suffix 'IRMMZ-T' against official Renesas documentation to confirm pinout compatibility and electrical tolerances. Confirm RoHS compliance status as required by your assembly specifications. Check for end-of-life notices or product change notifications prior to final design approval. Ensure the 10-DFN footprint matches your PCB layout guidelines exactly.

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

Select this component when dual isolated 300mA outputs are required in a minimal footprint. Consider the 2.3V minimum input voltage constraint for battery discharge profiles. Evaluate the 3V fixed output options against system rail requirements. Verify that the 1µF to 10µF ceramic capacitor stability requirement aligns with your decoupling strategy.

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

This part belongs to the ISL9000 series of low dropout regulators designed for portable applications. It shares architectural similarities with other Intersil/Renesas LDOs but is distinct in its dual-output configuration. The series emphasizes low noise and high PSRR for sensitive RF and analog loads. It represents a transition point in Renesas's portfolio following the Intersil acquisition.
