LM2576T-5V 3A Buck Switching Voltage Regulator (TO-220)
The LM2576T-5V is a monolithic, high-efficiency DC-DC buck (step-down) switching regulator designed to provide a stable 5V output at up to 3A continuous load current. Housed in a rugged TO-220 package, it delivers reliable power conversion with excellent line/load regulation, making it ideal for Arduino and Raspberry Pi power solutions, embedded microcontroller systems, and general electronics components and modules.
✨ Key Features
- Fixed 5V output with stable regulation
- 3A peak output current capability
- High efficiency up to 92% for reduced heat and improved battery life
- Integrated thermal shutdown 🛡️ for over-temperature protection
- Short-circuit protection 🛡️ for fault-tolerant operation
- Low-power standby mode via ON/OFF control pin (logic-level shutdown)
- Industry-standard TO-220 package for easy heatsinking
- Fixed-frequency switching design for simplified external component selection
🧪 Technical Specifications
- Output Voltage: 5V (fixed)
- Output Current: up to 3A
- Efficiency: up to 92% (application-dependent)
- Package Type: TO-220
- Topology: Step-down (buck) switching regulator
- Control: ON/OFF pin for enable/standby control from a microcontroller
🔎 Notes for Designers
- Requires external components: inductor, Schottky diode, and input/output capacitors (select per datasheet for desired ripple and load conditions).
- Ensure adequate heatsinking and PCB thermal design to support 3A loads.
- Follow recommended layout guidelines to minimize switching noise and output ripple.
