LB1117AADB330产品介绍

LB1117
1.0A Low Dropout Positive Regulators
General Description
The LB1117 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 LB1117 is set at the
factory and trimmed to ±1%. The LB1117 is stable with a aluminum electrolytic capacitor of 10uF.
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.
