Descriptions

The DIO7708 is a 300 mA LDO linear voltage

regulator. It is a very stable and accurate device

with an ultra−low quiescent current consumption

(typ. 4 µA over the full temperature range) and a

wide input voltage range (up to 30 V). The

regulator incorporates several protection features

such as thermal shutdown and current limiting.

Applications
