9 Voltage Regulators You Should NEVER Use in Your Product

Introduction and the 7800 Series00:00:00

Explanation of why common hobbyist regulators often fail in professional products due to thermal issues, poor efficiency, and large size. The 7800 series is criticized for its high dropout voltage and dated performance.

LM2596 and MC34063 Switching Regulators00:03:16

Discussion on why the LM2596 is unsuitable due to low switching frequency and EMI issues, and why the MC34063 is difficult to compensate and unstable for production designs.

No-Name ICs and the AMS 111700:05:21

Warnings against using unbranded components with unreliable datasheets. The AMS 1117 is highlighted as a common but problematic choice for modern applications due to poor transient response.

Cheap Modules, HT7333, and LM31700:07:43

Analysis of the risks associated with unshielded switching modules, the low-current limitations of the HT7333 series, and the failure modes of the adjustable LM317 regulator.

MCP1700 and Conclusion00:11:53

The MCP1700 is examined for its poor transient response despite low quiescent current. The video concludes by emphasizing the importance of matching regulator specifications to real-world load requirements rather than single headline figures.
