LP5907QMFX-4.5Q1

The LP5907-Q1 is a low-noise LDO that can supply 250 mA of output current. Designed to meet the requirements of RF and analog circuits, the LP5907-Q1 provides low noise, high PSRR, low quiescent current, and low line or load transient response figures. Using new innovative design techniques, the LP5907-Q1 offers class-leading noise performance without a noise bypass capacitor and the ability for remote output capacitor placement. The device is designed to work with a input and a output ceramic capacitor (no separate noise bypass capacitor is required). This device is available with fixed output voltages from 1.2 V to 4.5 V in 25-mV steps.
