Overview
The PX3143HDMSM1385XTMA1 is an automotive-grade linear voltage regulator manufactured by Infineon Technologies. It delivers a fixed 3.3 V output with a tight tolerance of ±1.5%. The device supports a maximum output current of 150 mA, making it suitable for powering sensitive electronic loads in demanding environments. Designed for robust performance, the component operates within an extended temperature range, ensuring reliability in automotive applications where thermal stability and precise voltage regulation are critical for system integrity.
Feature Summary
- Automotive-grade construction for high reliability
- Fixed 3.3 V output with ±1.5% precision
- Linear regulation topology for low noise
Applications
- Powering microcontrollers in automotive systems
- Supplying sensors requiring stable 3.3 V rails
- Automotive infotainment subsystems
Procurement Notes
Verify the complete part number including suffixes against official Infineon documentation to ensure correct package and temperature grade. Confirm RoHS compliance status through manufacturer datasheets. Cross-reference ordering information directly with authorized distributors to avoid counterfeit components. Validate that the specific variant matches the required electrical specifications for the target application.
Selection Notes
Select this component when a fixed 3.3 V rail is required with high accuracy and automotive qualification. Consider the 150 mA current limit for load sizing. Evaluate thermal dissipation requirements based on input-output voltage differential and load current. Ensure compatibility with automotive environmental standards compared to industrial or commercial alternatives.
Part Context
This regulator belongs to Infineon's portfolio of power management solutions designed for automotive electronics. It complements other linear regulators in the series offering different voltage outputs and current capabilities. The component addresses the need for stable, low-noise power supplies in vehicles where switching regulators may introduce unacceptable electromagnetic interference.
Replacement Considerations
Check for direct pin-compatible substitutes within the same Infineon family offering identical 3.3 V output and current ratings. Verify that alternative parts meet the same automotive quality standards and temperature ranges before substitution.
