The 8682L sits between low-cost TP4056 (larger package) and higher-performance MCP73831 (more expensive).

A typical application from the datasheet requires minimal external components: The 8682L is ideal for a 300mAh to

Stability note: Unlike some modern LDOs, the 8682L requires output capacitors with controlled ESR. Ultra-low ESR ceramic caps alone may cause oscillations; adding a 0.5Ω resistor in series is a common fix.

While you should always verify the exact datasheet for your specific batch, the standard specifications for this IC family typically include: Avoid it if: | Parameter | 8682L |

The 8682L remains a solid choice for medium-current, low-dropout applications where simplicity and robust protection matter more than ultra-low quiescent current. Its forgiving input tolerance and built-in reverse protection make it ideal for automotive, industrial control, and hobbyist power supplies. For new designs, always consult the manufacturer’s latest datasheet for package options (SOT-223, TO-252, DPAK) and revision-specific changes.

Best used for: Post-regulation of switching supplies, battery-powered equipment, audio/video analog rails, and 5V/3.3V microcontrollers.
