ISL9007IUJZ

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

The ISL9007IUJZ is a fixed-output low-dropout (LDO) linear voltage regulator manufactured by Renesas Electronics Corporation. It provides a stable 2.8V output with a maximum load current of 400mA. The device operates within an input voltage range of 2.3V to 6.5V and features a typical dropout voltage of 200mV at full load. Key electrical specifications include a power supply rejection ratio (PSRR) of 75dB at 1kHz, output noise below 30µVRMS, and quiescent current of 50µA. The unit offers ±1.8% output voltage accuracy across the operating temperature range of -40°C to +85°C and is housed in an 8-lead MSOP package.

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

Verify component authenticity through authorized Renesas distributors or direct manufacturer channels. Confirm RoHS compliance status and check for end-of-life notifications, as availability may be limited. Ensure proper ESD handling during storage and installation. Validate that the specific suffix matches the required voltage and package configuration before procurement.

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

Select this component when a fixed 2.8V rail is required with high current capability up to 400mA. It is suitable for applications demanding low noise and high PSRR in space-constrained designs using the MSOP package. Consider thermal dissipation requirements based on the input-output voltage differential and load current. Verify compatibility with ceramic capacitors between 1µF and 10µF for stability.
