1.5A LOW DROPOUT VOLTAGE CMOS REGULATOR
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.
Features
• High Output Current Up to 1.5A
• Output Voltage Available in ADJ(0.8V)
• Stable with a Ceramic Output Capacitor
• Dropout Voltage: 300mV@1.5A, Vo = 3.3V
• Low Quiescent Current
• Over Temperature Shutdown
• Short Circuit Protection
• Low Temperature Coefficient
• Standard SOP-8 Packages
• Pb-Free Package
