PAM3115
General Description
The PAM3115 is a 1.5A CMOS LDO regulator that
features a low quiescent current, ultra low input,
output and dropout voltages, as well as over
temperature shutdown. It is available in SOT-223 ,
TO-252 and SOP-8(exposed pad) packages. The
fixed output voltage of the PAM3115 is set at the
factory and trimmed to ± 2%. The PAM3115 is
stable with a ceramic output capacitor of 1.0uF
or higher.
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 voltages.
