ISL9000AIRMNZ

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

The ISL9000AIRMNZ is a dual-channel low-dropout (LDO) linear voltage regulator manufactured by Renesas Electronics Corporation. It operates within an input voltage range of 2.3V to 6.5V and provides two fixed positive output voltages: 1.8V and 3.0V. Each channel supports a maximum output current of 300mA. The device features a typical dropout voltage of 250mV at full load, with a maximum specified at 400mV. Quiescent current is maintained at 32µA, while maximum supply current reaches 52µA. Protection mechanisms include overcurrent limiting, thermal shutdown, and undervoltage lockout (UVLO). Control functions are provided via Enable and Power On Reset (POR) pins. The component is housed in a 10-pin VFDFN package measuring 3.00mm x 3.00mm with a height of 0.88mm.

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

Verify the specific suffix 'M' indicates the correct output voltage combination of 1.8V and 3.0V, as other suffixes may denote different voltage pairs or packages. Confirm the RoHS compliance status and lead-free plating specifications required for your assembly process. Check for any recent Product Change Notifications (PCNs) regarding manufacturing site changes or material updates. Ensure the ordering quantity matches the manufacturer's standard tube packaging configuration. Validate that the component meets all environmental and export classification requirements for your region.

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

Select this component when dual independent LDO channels are required in a compact footprint. The 300mA per channel rating suits moderate load applications. Verify that the input voltage remains above the sum of the highest output voltage and the maximum dropout voltage across the entire operating temperature range. Consider the 32µA quiescent current impact on total system power budget. Ensure thermal dissipation capabilities of the PCB layout can handle the power loss under maximum load conditions.

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

The ISL9000AIRMNZ belongs to the ISL9000A series of dual LDO regulators from Renesas. This series is designed for applications requiring high power supply rejection ratio (PSRR) and low noise performance. The device integrates advanced biasing techniques to maintain stability with small ceramic capacitors. It is part of Renesas' broader portfolio of power management integrated circuits aimed at improving efficiency in portable and industrial electronics.

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

Direct substitutes must match the dual-channel configuration, 300mA output current, and compatible pinout. Verify equivalent dropout voltage characteristics and PSRR performance. Check for identical protection features and control logic compatibility. Ensure the replacement package dimensions fit the existing PCB footprint without mechanical interference.
