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

What is the purpose of the CE pin on the XC6216B922MR-G?

The CE (Chip Enable) pin controls the ON/OFF state of the regulator. Applying a high voltage activates the output, while a low voltage engages the standby mode, reducing power consumption to approximately 0.01μA.

Does the XC6216B922MR-G require external resistors to set the output voltage?

No, the XC6216B922MR-G is a fixed-output type. The output voltage is internally set to 2.2V via laser trimming technology and does not require external resistors.
