ISL9000IRMMZ-T

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

The ISL9000IRMMZ-T is a dual low-dropout (LDO) linear voltage regulator manufactured by Renesas Electronics, formerly Intersil. It features two independent positive fixed outputs with a maximum output current of 300mA per channel. The device operates within an input voltage range of 2.3V to 6.5V and provides fixed output voltages of 2.8V and 3.0V. It utilizes a 10-DFN (3x3mm) package with an exposed pad for thermal management. Key electrical specifications include a maximum dropout voltage of 0.4V at 300mA load, a quiescent current of 32µA, and a load regulation of 0.1%. The unit supports operation from -40°C to +85°C.

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

Verify the exact suffix configuration against the datasheet to ensure correct output voltage combinations and package type. Confirm RoHS compliance status as manufacturing sites may vary. Check for End-of-Life (EOL) notifications or Product Change Notifications (PCN) prior to final design approval. Ensure ESD handling procedures are followed due to the small DFN package form factor.

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

Select this component when a compact dual-output solution is required for space-constrained designs. Compare total power dissipation capabilities against the expected thermal environment of the application. Evaluate the specific output voltage options available in the series to match system logic levels without external resistors. Consider the trade-off between the low quiescent current and the required line/load regulation performance.
