DESCRIPTION
The GS-R12VXXX1.5 series is a family of high effi-
ciency step down switching voltage regulator, de-
signed to replace linear regulators.
The foot print of GS-R12V perfectly fits a standard
TO220 package.
Based on STM L5973 device, this non isolated family
of regulators are suitable for the full spectrum of ap-
plications including telecom, industry, computer and
distributed power system applications having a wide-
ly ranging input voltage.
