A Product Line of Diodes Incorporated PAM3110 1.5A LOW DROPOUT VOLTAGE CMOS REGULATOR Description Pin Assignments The PAM3110 is a 1.5A CMOS LDO regulator that features a low quiescent current and low dropout voltages, as well as over temperature shutdown. The fixed output voltage of the PAM3110 is set at the factory and trimmed to 1.5%. The PAM3110 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. PAM3110 is available in SOT-223, TO-252 and TO-263-2L package. Features DSP, FPGA and Microprocessor Power Supplies Output Voltages:1.2V, 1.5V,1.8V, 2.5V 3.3V and 5.0V Stable with a Ceramic Output Capacitor Dropout Voltage: 400mV 1.5A Low Quiescent Current Over Temperature Shutdown Short Circuit Protection Low Temperature Coefficient Pb-Free Packages Applications DSP, FPGA and Microprocessor Power Supplies SATA Power Supply LCD TV/Monitors Wireless Devices Communication Devices Portable Electronics Post Regulator for SMS 1 of 13 September 2013 PAM3110 Diodes Incorporated www.diodes.com Document number: DSxxxxx Rev. 2 - 2 A Product Line of Diodes Incorporated PAM3110 Typical Applications Circuit Pin Configuration and Description Pin Number Pin Name Function SOP-8(EP) W-DFN3x3-10 7, 8, 9 Supply Input Voltage.
