What is it?

A breadboard friendly power overvoltage protection module. The protection voltage limit is jumper selectable for 3.3V or 5V. If the input voltage exceeds the limit then the output is disconnected from power. Use it to protect sensitive components from damage due to overvoltage.

This is not a voltage regulator; this goes after the voltage regulator or buck/boost power module. It protects your components in the event of a power supply regulation failure.

Specifications

• 3.3V limit cutoff voltage is 3.6V.
• 5V limit cutoff voltage is 5.5V.
• Input reverse polarity protected by clamp diode*.
• Input overvoltage protected by clamp diode*.

*Warning - Continuous reverse voltage, over voltage, or low voltage (short circuit) conditions can overheat and damage the module.

Absolute Maximum Ratings

• 12V input voltage.
• 2.5A maximum current.

Recommended Operating Conditions

• 2.5A maximum current at 5V.
• 2.0A maximum current at 3.3V.
