Preliminary Datasheet
LP3993
200mA,Ultra-low Noise LDO Regulator
General Description
The LP3993 is designed for portable applications with
demanding performance and space requirements. The
LP3993 performance is optimized for high voltage
systems to deliver ultra low noise and low quiescent
current. Regulator ground current increases only
slightly in dropout, further prolonging the input system
life. The LP3993 also works with low-ESR ceramic
capacitors, reducing the amount of board space
necessary for power applications, critical in hand-held
wireless devices. The other features include ultra low
dropout voltage, high output accuracy, current limiting
protection, and high ripple rejection ratio.
