LM 2576s Voltage Regulator Module — 5V, 3A, 52 kHz

The LM 2576s Voltage Regulator Module delivers steady, regulated 5V output with a maximum output current of 3A, designed for robust power management in a wide range of electronic systems. Its switching topology operates at 52 kHz and provides considerably higher efficiency than comparable linear regulators, reducing heat generation and improving battery life in portable or battery-powered applications. Key specifications and protections include: Output voltage: 5V, optimized for microcontrollers and common digital circuits. Switching frequency: 52 kHz, which contributes to reduced output ripple and improved overall efficiency. Maximum output current: 3A, supporting moderate to high power loads in embedded and consumer electronics. Input voltage range: 7V to 40V, enabling flexible power-source options from battery stacks to regulated supplies. Protection features: thermal shutdown and overload/current limiting to protect the regulator and load under fault conditions. Compared with traditional linear regulators, the LM 2576s minimizes power loss by switching energy rather than dissipating it as heat, which makes it a practical choice for applications where efficiency and thermal performance are important. The module's overload and thermal protections enhance reliability by preventing damage during abnormal operating conditions. Typical applications include microcontroller systems, power supplies for sensors and modules, embedded devices, and other circuits that require a stable 5V rail with efficient power conversion. The LM 2576s is a dependable component when consistent voltage and durable operation are required in both industrial and consumer electronic designs.
