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

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.
