ISL9003AIEBZ-T

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

The ISL9003AIEBZ-T is a fixed-output linear low-dropout regulator (LDO) manufactured by Intersil, designed for high-performance power management applications. It provides a fixed output voltage of 2.5V with a maximum continuous load current capability of 150mA. The device features an input voltage range from 2.3V to 6.5V and maintains a maximum dropout voltage of 0.4V at full load. Key electrical specifications include a quiescent current of 40µA and a maximum supply current of 57µA. It operates within a temperature range of -40°C to +85°C and utilizes a SC-70-5 surface-mount package.

• Camera modules demanding high signal integrity

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

Verify the specific suffix 'EBZ' against official Intersil documentation to confirm package type and tape/reel configuration. Ensure compatibility with RoHS standards and lead-free requirements if applicable. Confirm availability status as distribution data may vary. Cross-reference the manufacturer part number with Renesas Electronics records following corporate acquisitions. Validate that the fixed 2.5V output aligns with target circuit design requirements before procurement.

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

Select this component when designing circuits that require a clean, stable 2.5V rail for sensitive analog or RF sections. The low noise profile makes it suitable for powering receivers where signal-to-noise ratio is critical. Consider the 150mA current limit for load requirements and verify that the input voltage remains within the 2.3V to 6.5V window. The SC-70-5 package offers space efficiency for compact mobile designs.
