Overview
The LD1117F33C is a fixed positive low-dropout linear voltage regulator manufactured by STMicroelectronics. It provides a nominal output voltage of 3.3 V with a maximum dropout voltage of 1.2 V at full load. The device supports a maximum output current of 1.3 A and operates within an input voltage range up to 15 V. It features excellent line regulation of 0.006% and load regulation of 0.01%. The component is housed in a TO-220FM package with three terminals and is rated for junction temperatures between -40 °C and 125 °C.
Feature Summary
- Fixed positive output voltage regulation
- Low dropout operation capability
- High thermal stability over extended temperature ranges
Applications
- Battery-powered systems requiring stable voltage rails
- Post-regulation for switching power supplies
- Portable equipment power management
Procurement Notes
Verify the specific suffix 'C' against official STMicroelectronics documentation to confirm compliance status and exact electrical tolerances. Ensure the TO-220FM package variant matches the required thermal dissipation needs for the target application environment.
Selection Notes
Select this component when a fixed 3.3 V rail is required with high current capacity up to 1.3 A. The TO-220FM package facilitates effective heat dissipation for higher power applications compared to smaller surface-mount alternatives.
Part Context
This part belongs to the LD1117 series of low-dropout regulators from STMicroelectronics. The series is designed for efficient voltage regulation in space-constrained designs, offering robust performance with minimal external components required for stable operation.
