General Description

The PAM3105 is a 0.5A 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 a SOT-89

package. The f ixed output voltage of the

PAM3105 is set at the factory and trimmed to

2.0%. The device 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. They

are particularly well suited for applications

requiring low input and output voltages.
