Overview
The LDI812C-3.3SFA is a fixed-output linear voltage regulator manufactured by Diotec Semiconductor, designed for low-power applications. It provides a stable 3.3 V output with a maximum current capacity of 50 mA. The device operates with an input voltage range up to 16 V and features a typical dropout voltage of 230 mV at the rated load. Packaged in a compact SOT-23-5 surface-mount format, it supports operation within a temperature range extending to +85 °C. Key electrical characteristics include a load regulation of 45 mV and a power dissipation rating of 600 mW.
Feature Summary
- CMOS-based architecture ensures low power consumption
- Fixed 3.3 V output voltage option available
- Compliant with RoHS, REACH, and Conflict Minerals regulations
Applications
- Battery-powered electronic devices requiring efficient voltage regulation
- General-purpose low-current logic supply circuits
- Portable consumer electronics with space constraints
Procurement Notes
Verify component authenticity through authorized Diotec Semiconductor distributors or certified suppliers. Confirm that the received parts match the LDI812C-3.3SFA designation and package type. Review the official datasheet for handling instructions regarding moisture sensitivity levels. Ensure compliance with relevant environmental directives such as RoHS and REACH before integration into final assemblies.
Selection Notes
Select this regulator when a fixed 3.3 V supply is required with a maximum load of 50 mA. The SOT-23-5 package suits designs with limited board space. Consider the 16 V maximum input voltage and 600 mW power dissipation limits during thermal analysis. Verify that the application environment remains within the specified operating temperature range for reliable performance.
Part Context
This component belongs to the LDI812C series of low-dropout regulators from Diotec Semiconductor. The series utilizes CMOS technology to achieve low quiescent current, making it suitable for battery-operated systems. The specific suffix indicates the fixed 3.3 V output variant housed in a standard SOT-23-5 surface-mount package.
Replacement Considerations
Cross-reference with other 3.3 V LDOs in SOT-23-5 packages offering similar 50 mA output current and 16 V input ratings. Verify pinout compatibility and thermal performance characteristics before substitution.
