LFC789D25CDR Allgemeine Beschreibung

The LFC789D25CDR streamlines the design process for dual power supplies by providing two independent controllers that drive external MOSFETs, forming low-dropout regulators. One controller is preset to regulate a 2.5-V output, while the other can be customized to regulate any desired output voltage through a reference input pin, facilitating the creation of tracking regulators essential for termination schemes. Designed to isolate heating effects of the external FETs, the controllers can effectively regulate output voltages within a ±2% tolerance across temperature and load variations. With its flexibility in component selection and topology, designers can tailor power supplies to their specific needs, enabling the creation of regulators with high current capabilities and low dropout potential with the right choice of power MOSFET. The LFC789D25CDR is available in 8-pin SOIC and compact TSSOP packages, suitable for operation in temperatures ranging from 0°C to 70°C
