ISL9003AIEJZ-T

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

The ISL9003AIEJZ-T is a fixed-output linear regulator manufactured by Renesas Electronics Corporation. It provides a fixed output voltage of 2.8V with a maximum continuous output current of 150mA. The device operates from an input voltage range up to a maximum of 6.5V. Key electrical specifications include a maximum dropout voltage of 0.4V at full load and a typical quiescent current of 40 µA. The component is housed in a SC-70-5 surface-mount package and supports an operating temperature range from -40°C to +85°C.

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

Verify the specific suffix 'EJ' confirms the 2.8V fixed output voltage variant before procurement. Confirm the manufacturer designation as Renesas Electronics Corporation, noting the historical Intersil lineage. Ensure the SC-70-5 package type matches the target footprint design. Validate RoHS compliance status against current regulatory requirements for the intended market.

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 150mA. Consider the 40 µA quiescent current for battery efficiency applications. Evaluate the 0.4V dropout voltage against the minimum available input voltage headroom. The SC-70-5 package offers a space-efficient solution for dense layouts compared to larger regulator packages.

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

This part belongs to the ISL9003 series of low-dropout linear regulators. The series is characterized by high accuracy and low noise performance suitable for sensitive analog circuits. The product line has been integrated into the Renesas portfolio following corporate acquisitions, maintaining technical continuity for existing designs.

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

Cross-reference with other ISL9003 variants offering different fixed output voltages if the 2.8V specification does not match the new design requirements. Verify pin compatibility when substituting with newer generations of LDOs from the same manufacturer family.
