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

How does the CE pin affect the standby current?

When the CE pin is pulled low (L level), the IC enters stand-by mode, reducing the supply current to less than 0.1 μA. In this state, the output voltage is pulled down to the VSS level via internal resistors.

What protection features are included in the XD6506B132MR-G?

The device includes a current limit circuit with a fold-back characteristic that also serves as a short protect for the output pin. Additionally, it features thermal shutdown protection to prevent damage during overload conditions.

Is the XD6506B132MR-G compatible with ceramic capacitors?

Yes, the series is designed to be compatible with low ESR ceramic capacitors. An output capacitor of 0.1 μF or larger is recommended for stable phase compensation.
