5V 1A DC-DC Step-Down Module – LM7805 Three-Terminal Regulator Replacement

5V 1A DC-DC Step-Down Module – LM7805 Three-Terminal Regulator Replacement

The classic LM7805 linear regulator works – but it wastes energy as heat. This 5V 1A DC-DC step-down module is a direct drop-in replacement that delivers the same stable 5V output with far greater efficiency. Less heat, less waste, and the same three-terminal footprint means you can swap it straight into your existing circuit without redesigning the board.

Electrical Specifications

• Output Voltage: 5V DC (fixed)
• Output Current: 1A (max)
• Input Voltage Range: 6.5V – 28V DC
• Efficiency: Up to ~85% (vs ~30–50% for LM7805 linear)
• Package: TO-220 compatible 3-pin footprint
• Low standby current, minimal heat generation

Key Features

• Drop-in LM7805 replacement – same 3-pin TO-220 footprint
• Switching regulator efficiency – runs cool without a heatsink in most applications
• Wide input voltage range – works with 9V, 12V, 24V supplies
• Stable 5V output for microcontrollers, sensors, and logic circuits
• Compact module design – easy to integrate

Typical Applications

• Arduino and microcontroller 5V power supply
• Replacing overheating LM7805 regulators in existing designs
• 12V to 5V conversion for automotive and industrial circuits
• DIY electronics power supply modules

Upgrade your 5V power supply from linear to switching – same footprint, better efficiency, cooler operation.
