Description
The GS-R12FP series is a family of high
efficiency step down switching voltage regulator,
designed to replace linear regulators.
Based on L5973AD device, this non isolated
family of regulators are suitable for the full
spectrum of applications including telecom,
industry, computer and distributed power system
applications having a widely ranging input
voltage.
