In electronics:
* Low Dropout Regulator: A type of voltage regulator that can maintain a stable output voltage even when the input voltage is very close to the output voltage.
In other contexts:
* Legal Department Order: Used in legal and judicial settings.
* Local Development Order: A planning document used in the UK.
* Lethbridge District Office: A regional office of a larger organization in Lethbridge, Canada.
* Lead Data Officer: A role responsible for data management and governance.
To determine the correct full form, you'll need more context. For example, if you saw "LDO" in a technical document about electronics, it would likely refer to a "Low Dropout Regulator." If you saw "LDO" in a legal document, it would likely refer to a "Legal Department Order."
Please provide more information about the context where you saw "LDO" so I can give you a more accurate answer.
