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

How does the CE pin function on the XC6210D31APR-G?

The CE pin on the D-series is active-low. Applying a Low signal activates the regulator, while a High signal or open state places the device in stand-by mode, reducing supply current to approximately 0.10μA.

What is the output voltage accuracy for the 3.1V setting?

For output voltages between 1.55V and 5.00V, the accuracy is specified as ±2%.
