ZLDO485: Wide Vin, 300 mA LDO

Description

The PAM3116 is a 1.5A CMOS LDO regulator that features a low quiescent current and low dropout voltages, as well as over temperature shutdown. The PAM3116 is stable with a ceramic output capacitor of 4.7μF 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 suitable for applications requiring low input and output voltages. PAM3116 is available in SOP-8 package.
