1.0A Low Dropout Positive
Regulators
General Description
The LA1117 is a low dropout three terminal
regulator that features a low quiescent current, low input, output and dropout voltages, as well as over temperature shutdown. The output voltage of the LA1117 is set at the factory and trimmed to ±1%. The LA1117 is stable with a ceramic output capacitor of 4.7uF. This family of
regulators can provide either a stand-alone power supply solution or act as a post
regulator for switch mode power supplies. They are particularly well suited for applications requiring low input and output voltage.
