1.5A, 3A LDOs Feature Tight Accuracy, Fast Transient Response and Extensive Protection


The NCP5915x, NCP5930x, NCP5830x series are high precision, very low dropout, low ground current voltage regulators that are capable of providing large load currents with a typical dropout voltage lower than 300mV. Internal protection features such as output current limit, thermal shutdown, and reverse output current protection assure robust power supply solution. Both adjustable and fixed output voltage options are available. Additional features include an enable function and output error flag.

Very good transient response, high PSRR and very low dropout make this device series an ideal choice for precision point of load (POL) applications and switch mode DC/DC post regulation.
