The LP5900 is a linear regulator capable of supplying 150-mA output current. Designed to meet the requirements of RF/Analog circuits, the LP5900 device provides low noise, high PSRR, low quiescent current, and low line transient response figures. Using new innovative design techniques the LP5900 offers class-leading device noise performance without a noise bypass capacitor.
The device is designed to work with 0.47-µF input and output ceramic capacitors (no bypass capacitor required).
The device is available in a DSBGA (YZR) package and a WSON package; also available in an extremely thin DSBGA (YPF) package.
