TI LP5907UVE-2.85/NOPB

The LP5907 is a low-noise LDO capable of providing an output current of up to 250 mA. This device is specifically designed for RF and analog circuits, meeting their requirements for low noise, high PSRR, low quiescent current, and low line or load transient response coefficients. The LP5907 uses innovative design techniques to provide excellent noise performance without the need for a noise bypass capacitor and supports remote placement of the output capacitor. This device can be used with a 1 μF input and a 1 μF output ceramic capacitor (no separate noise bypass capacitor is required). Its fixed output voltage ranges from 1.2 V to 4.5 V (in 25 mV steps).
