LP5912 - Texas Instruments

LP5912 Low-noise LDO

The LP5912 is low-noise LDO that can supply up to 500 mA of output current. Designed to meet the requirements of RF and analog circuits, the LP5912 device provides low noise, high PSRR, low quiescent current, and low line and load transient response. The LP5912 offers class-leading noise performance without a noise bypass capacitor and with the ability for r.
