Reverse polarity input protection?

Pololu Adjustable Step-Up Voltage Regulator U1V11A

Considering use of it powered by 18650 Lithium cell to get 4.0-5.5 volts.

If the customer inserts the battery backwards, is the regulator protected?


As mentioned in the U1V11A regulator’s product page description, it does not have reverse-voltage protection.

Some of our regulators have built-in reverse voltage protection circuits, such as the U3V50ALV, but they are significantly larger boards that are designed to handle more power.
