DESCRIPTION
The TDA1154 is a monolithic integrated circuit in-
tended for speed regulation of permanentmagnet
dc motors used in record players, tape recorders,
cassette recorders and toys.
Thecircuitoffersanexcellentspeedregulationwith
much higher power supply, temperatureand load
variations than conventional circuits built around
discrete components.
