Description
The GS-R24F series is a family of high efficiency
step down switching voltage regulator, designed
to replace linear regulators.
Based on ST L5973 device, these non isolated
regulators are suitable for various applications,
including telecom, industry, computer and
distributed power supply system having a wide
range input voltage.
