LF90CDT

Overview

The LF90CDT is a positive LDO voltage regulator from STMicroelectronics providing a fixed 9.0V output with a maximum current of 0.5A. It features a maximum dropout voltage of 0.7V at full load. Designed for automotive applications, it connects directly to car batteries and supports standby microprocessor control-unit systems.

Feature Summary

Direct connection capability to automotive battery systems
Optimized for standby microprocessor control-unit architectures
Fixed 9.0V regulated output stability

Applications

Automotive standby microprocessor control units
Car battery connected power regulation systems
Low-dropout voltage regulation in automotive electronics

Procurement Notes

Verify the specific suffix (e.g., -TR) against your reel requirements. Confirm package type matches design constraints. Ensure input voltage exceeds 9.7V for proper regulation. Check temperature ratings for automotive grade compliance. Validate pinout compatibility before integration.

Selection Notes

Select this component when a stable 9V supply is required for automotive microprocessors. The low dropout characteristic ensures efficiency under varying battery conditions. Consider thermal dissipation needs at 0.5A loads. Verify that the fixed output voltage aligns with downstream logic levels.

Part Context

This part belongs to STMicroelectronics' linear regulator portfolio, specifically targeting automotive standby applications. It complements other LF90 series variants offering different voltages or packages. The device addresses the need for robust voltage regulation in harsh automotive environments.

Replacement Considerations

Cross-reference with LF90ABDT-TR or LF90CPT-TR for similar specifications. Verify if alternative suffixes indicate identical electrical performance. Ensure package dimensions match existing PCB footprints during substitution.
