Typical Application
The LP5907 is designed to meet the requirements of RF and analog circuits, by providing low noise, high PSRR, low quiescent current, and low line or load transient response figures. The device offers excellent noise performance without the need for a noise bypass capacitor and is stable with input and output capacitors with a value of 1μF. The LP5907 delivers this performance in industry standard packages such as DSBGA, X2SON, and SOT-23 which, for this device, are specified with an operating junction temperature (T J ) of -40°C to 125°C.
