Description
The LD1117S33CTR is a high-performance, low-dropout (LDO) voltage regulator designed to provide a steady, fixed 3.3V output. Capable of delivering up to 800mA of output current, it is a versatile and essential component for powering digital logic circuits, microcontrollers, and various wireless modules that require a clean, reliable power supply.
Because it is a low-dropout regulator, it maintains regulation even when the input voltage is only slightly higher than the desired output, which significantly improves energy efficiency compared to traditional regulators. This model is housed in a compact SMD-4 package, making it perfect for modern, space-constrained PCB designs while providing excellent thermal management for reliable, long-term operation.
Key Features
- Fixed 3.3V Output: Pre-configured for a standard 3.3V rail, simplifying your circuit design by eliminating the need for external setting resistors.
- 800mA Current Capacity: Provides ample power for a wide range of devices, including demanding sensors and microcontrollers.
- Low Dropout Performance: Operates efficiently with minimal voltage difference between input and output, reducing heat and energy waste.
- Integrated Protection: Includes internal thermal shutdown and current-limiting protection to shield the regulator and your electronics from overloads.
- Compact SMD-4 Package: A small form factor that fits easily into modern, miniaturized electronic board layouts.
Application
- Embedded Systems: Ideal for powering 3.3V microcontrollers (e.g., ARM, ESP32) and peripheral communication modules.
- Wireless Modules: Provides the stable voltage required for consistent operation of Bluetooth, Wi-Fi, and RF modules.
- Consumer Electronics: Great for battery-powered devices where efficiency and consistent performance are critical.
- Industrial Controllers: Provides clean power for logic circuits and control signals in factory automation.
- DIY Hobbyist Projects: A go-to component for anyone needing a solid, easy-to-use 3.3V power source for custom projects.
