LP5912-1.2DRVT

The LP5912 is a low-noise LDO capable of providing up to 500mA output current. Designed to meet the requirements of RF and analog circuits, the LP5912 features low noise, high PSRR, low quiescent current, and low line/load transient response. The LP5912 delivers excellent noise performance without a noise bypass capacitor and supports remote placement of the output capacitor. This device is compatible with 1μF input and 1μF output ceramic capacitors (no separate noise bypass capacitor required). Fixed output voltage ranges from 0.8V to 5.5V in 25mV increments.
