PAM3105
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 fixed output voltage of the PAM3105 is set at the factory and trimmed to ± 2.0%. The device 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.
