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 4.7µF 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. PAM3110 is available in SOT-223, TO-252 and TO-263-2L package.


· Minimum Guaranteed Output Current: 1.5A · Low Dropout Voltage: 375mV at IOUT=1.5A · Output Accuracy: ±1% · Low Ground Current · Internal Current and Thermal Limit · Reversed-battery and Reversed-lead Insertion Protection · Fast Transient Response · TTL/CMOS Compatible Enable Pin
