ISL9007IUJZ-T

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

The ISL9007IUJZ-T is a high-performance linear voltage regulator IC from Renesas Electronics Corporation, housed in an 8-MSOP package. It provides a fixed positive output voltage of 2.8V with a continuous load current capacity of 400mA. The device features a typical dropout voltage of 0.25V and a maximum of 0.4V at full load. It operates within a temperature range of -40°C to 85°C. Key electrical characteristics include a typical quiescent current of 50µA and a maximum standby current of 1µA. The regulator offers a high Power Supply Rejection Ratio (PSRR) of 75dB and maintains low output noise below 30µVRMS.

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

Verify the exact suffix configuration against official Renesas documentation before procurement, as ordering codes may denote specific tape-and-reel quantities or packaging variations. Confirm that the fixed 2.8V output aligns with your system design requirements. Check for discontinued status updates, as some variants like the ISL9007IUJZ-T may have lifecycle changes. Ensure compatibility with your PCB footprint for the 8-MSOP package.

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

Select this component when a fixed 2.8V rail is required with moderate current demands up to 400mA. It is suitable for designs prioritizing low quiescent current to extend battery life. Consider its thermal performance in the MSOP package if ambient temperatures approach the upper limit of 85°C. Compare its PSRR specifications against other LDOs if your application involves significant input voltage ripple.

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

This part belongs to the ISL9007 family of high-current low-dropout regulators produced by Renesas Electronics. The family includes various fixed voltage options such as 2.5V, 2.85V, and 3.3V. These regulators are designed for applications requiring high PSRR and low noise. The IUJZ-T designation specifically indicates the 2.8V version in an 8-MSOP package with tape-and-reel packaging.

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

Direct substitutes include other ISL9007 variants with different fixed output voltages (e.g., ISL9007IUJZ for 3.3V) if voltage adjustment is possible in the design. Cross-reference with Renesas' current portfolio for equivalent LDOs with similar 400mA output and MSOP8 packaging. Verify pin compatibility and thermal characteristics before swapping.
