FSP2161
„ GENERAL DESCRIPTION
The FSP2161 is a 1.5A CMOS LDO regulator that
features a low quiescent current, ultra low input, output
and dropout voltages, as well as over temperature
shutdown. It is available in TO252 and TO263
packages. The fixed output voltage of the FSP2161 is
set at the factory and trimmed to ±2%. The FSP2161 is
stable with a ceramic output capacitor of 1.0uF 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 well suited for applications requiring low
input and output voltage
