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

How does the CE pin function operate for the XC6210D series?

For the XC6210D series, the CE pin is active-low. The regulator turns on when the CE pin voltage is low and enters standby mode when the voltage is high. This specific type does not have an internal pull-up resistor.

What is the minimum output capacitor requirement for stable operation?

For output voltages between 1.80 V and 5.00 V, a minimum output capacitor of 1.0 μF is recommended. For lower output voltages (0.80 V to 1.45 V), a minimum of 6.8 μF is required.
