ISL9000AIRJMZ-T

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

The ISL9000AIRJMZ-T is a dual-channel low-dropout linear regulator manufactured by Renesas Electronics Corporation. It provides two independent positive fixed output voltages of 2.8V and 3.0V, each capable of delivering up to 300mA of output current. The device operates with an input voltage range up to a maximum of 6.5V. Key electrical parameters include a maximum dropout voltage of 0.4V at 300mA for one channel and 0.325V at 300mA for the other. Quiescent current is specified at 32µA, with a maximum supply current of 52µA. The component is housed in a 10-VFDFN package with dimensions of 3x3mm and a height of 0.88mm.

• Embedded circuits utilizing microcontrollers or memory components with specific voltage requirements.

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

Verify the exact suffix designation when sourcing replacements, as variations may indicate different packaging formats such as tape-and-reel versus tube. Confirm that the replacement part maintains the same output voltage combination of 2.8V and 3.0V. Ensure the substitute component supports the required 300mA per channel load current and fits within the available PCB space defined by the 10-DFN footprint. Check for RoHS compliance if environmental regulations apply to your manufacturing process.

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

Select this component when a compact solution is needed to generate two distinct fixed voltages from a single input source. It is suitable for designs where low noise and high power supply rejection ratio are critical for signal integrity. Consider the thermal performance of the VFDFN package under full load conditions. Verify that the input voltage never exceeds the 6.5V absolute maximum rating to prevent device damage.

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

This device belongs to the ISL9000 series of dual LDO regulators from Renesas. The series is characterized by its small form factor and integrated protection features. Similar parts in the family may offer different fixed output voltage combinations or varying current capabilities. The 'AIRJ' suffix typically denotes specific output voltages and temperature grade variants within the broader product line.

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

Direct substitutes must match the 2.8V/3.0V output configuration and 300mA current rating. Compatible alternatives include other dual LDOs in 10-DFN packages from Renesas or other manufacturers, provided they support the same input voltage range and pinout compatibility.
