Voltage Regulators - Linear, Low Drop Out (LDO) Regulators FAQ

How does the enable pin function?

The EN pin is CMOS/TTL compatible; applying a logic-high signal greater than 2V enables the regulator, while a logic-low or open state shuts it down.

What is the purpose of the BYP pin?

Connecting an external capacitor to the BYP pin reduces output noise, enabling ultra-low noise performance for sensitive applications.
