General Description
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.
