1.5A LOW DROPOUT VOLTAGE CMOS REGULATOR
Description Pin Assignments
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 4.7F 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.
