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

What is the function of the CBYP pin?

The CBYP pin is used to bypass the internal reference voltage to ground with a capacitor to reduce output noise and increase power supply rejection.

How are the regulators enabled?

Each regulator has a separate active-high enable input (EN1 and EN2). A logic high level enables the respective output, while a logic low disables it.
